RESUMO

Introdução: A demanda por cirurgia para correção de ginecomastia tem aumentado em função da grande quantidade de pacientes submetidos a tratamentos bariátricos. A maioria destes pacientes requerem grande remoção do excesso de pele, tecido gorduroso e reposicionamento do complexo areolopapilar, assim como adequação do volume da aréola. O objetivo deste estudo é descrever a técnica de correção de ginecomastia grau III através de cicatriz horizontal sem cicatriz vertical, com reposicionamento do complexo areolopapilar. Método: Estudo prospectivo de 27 pacientes masculinos com diagnóstico de ginecomastia grau III da classificação de Simon, operados em clínica particular, entre janeiro de 2013 e agosto de 2020, pela técnica de cicatriz horizontal com transposição do complexo areolopapilar e sem cicatriz vertical. Resultados: Foram operados 27 pacientes, num período de 7,5 anos, todos ex-obesos, submetidos previamente a tratamento de perda de peso. A idade variou de 17 a 74 anos, média etária de 52 anos. O peso das peças removidas variou de 175 a 758 gramas, média de 376 gramas. As complicações foram: 1 caso de hematoma tardio (3,7%), 1 caso de seroma (3,7%) e 2 casos de cicatriz hipertrófica (7,4%). Conclusão: O tratamento cirúrgico da ginecomastia grau III através da técnica de cicatriz horizontal, sem cicatriz vertical e com reposicionamento do complexo areolopapilar demonstrou ser efetivo, com baixa morbidade e bons resultados estéticos.

Introduction: The demand for surgery to correct gynecomastia has increased due to the many patients undergoing bariatric treatments. Most patients require extensive removal of excess skin, and fatty tissue, repositioning the nipple-areolar complex, and adjusting the areola volume. This study aims to describe the correction technique for grade III gynecomastia using a horizontal scar without a vertical scar, with repositioning of the nipple-areolar complex. Method: Prospective study of 27 male patients diagnosed with Simon grade III gynecomastia, operated in a private clinic between January 2013 and August 2020, using the horizontal scar technique with transposition of the nipple-areola complex and without a vertical scar. Results: 27 patients underwent surgery over 7.5 years, all ex-obese, previously submitted to weight loss treatment. Age ranged from 17 to 74 years, mean age of 52 years. The weight of the removed parts ranged from 175 to 758 grams, an average of 376 grams. Complications were 1 case of late hematoma (3.7%), 1 case of seroma (3.7%), and 2 cases of hypertrophic scarring (7.4%). Conclusion: Surgical treatment of grade III gynecomastia using the horizontal scar technique, without a vertical scar and with repositioning of the nippleareolar complex, proved to be effective, with low morbidity and good aesthetic results.

A taxa de complicações maiores foi de 3,8%. Houve uma reoperação (3,8%) no período de acompanhamento. O peso médio das mamas foi de 1.136 gramas, a idade média de 27 anos e 9 meses, índice de massa corporal médio de 26,6kg/m2 e 73% dos pacientes receberam terapia com hormônio masculino previamente à cirurgia. Conclusão: A mastectomia masculinizadora é um procedimento seguro, com boa reprodutibilidade e traz resultados estéticos satisfatórios.

■ ABSTRACT Introduction: Masculinizing mastectomy is generally the first, most important and often the only surgical procedure for gender reassignment in male transsexuals. The objective is to describe and systematize the steps of the technique used by the author of the double-incision mastectomy associated with a free graft from the nipple-areola complex. Methods: Retrospective review of 26 patients who underwent masculinizing mastectomies (total of 52 breasts), performed using the technique used by the author, between November 2013 and January 2018. Results: 84.6% of patients had surgery with a final horizontal scar in the inframammary fold, and 15.4% evolved with a final inverted "T" scar. The rate of major complications was 3.8%. There was one reoperation (3.8%) in the follow-up period. Mean breast weight was 1,136 grams, mean age was 27 years and nine months, mean body mass index was 26.6 kg/m2, and 73% of patients received male hormone therapy before surgery. Conclusion: Mastectomy is a safe procedure, with good reproducibility and brings satisfactory aesthetic results.

RESUMO

BACKGROUND: Male tuberous breast is an exceedingly rare condition that not fit properly into the majority of existing classifications of gynecomastia. This deformity has been categorized by Cordova and Moschella as gynecomastia grade III; however, they do not make any reference to the isolated tuberous deformity of the nipple-areola complex (NAC). Considering that the areolar area is the main ''esthetic unit'' in the male chest, surgical correction of the isolated tuberous NAC deformity can be challenging. There is a belief that this deformity is unsuccessfully corrected when approached through a limited periareolar incision at the lower pole. A complete periareolar incision, with a concentric excision of excess areolar skin, is usually required leaving an unnatural-looking round periareolar scar on the male thorax. METHODS: We describe a variation of a surgical technique for the correction of a male tuberous NAC deformity in a teenager who rejected a conspicuous round periareolar scar after surgery. This modification combines a conventional lower hemiareolar approach with a percutaneous intradermal purse-string suture in the superior areolar margin to reduce the areolar diameter, avoiding an evident circumareolar scar. RESULT: At the six-month follow-up, areolar widening or tuberous deformity relapse was not observed. The patient felt satisfied with the outcome. CONCLUSION: The use of percutaneous intradermal purse-string periareolar suture for correction of this rare deformity is a simple and reproducible surgical technique that could help to obtain a better cosmetic result by restoring the contour of the male chest while minimizing the visibility of the residual scar.

RESUMO

La ginecomastia, definida como el crecimiento del tejido glandular mamario en los hombres, aparece desde la etapa neonatal hasta la senil, puede ser unilateral o bilateral, y es de causa multifactorial, incluyendo aquellos pacientes asociados al uso de medicamentos, donde predomina un desbalance en la relación testosterona­estrógeno. Relativamente, la idiopática es la más frecuente. La mayoría involucionan espontáneamente, las neonatales por perdida del influjo transplacentario en las primeras semanas, y las puberales entre 12 a 24 meses. Se presenta como un aumento del tamaño mamario, asintomático o con hipersensibilidad por inflamación durante el crecimiento del tejido fibroglandular mamario, con una repercusión psicológica enorme, sobre todo en la etapa de la adolescencia. El estudio y manejo es interdisciplinario y se ofrece de acuerdo con las condiciones y la etiología. Aquellos pacientes púberes en quienes no involuciona reciben tratamientos médicos, o tratamientos quirúrgicos cuando falla la terapéutica o hay presión social, e incluso radioterapia en casos donde desarrollan ginecomastia con hipersensibilidad al tratamiento hormonal del cáncer de próstata

Gynecomastia, defined as the growth of breast glandular tissue in men, appears from the neonatal to senile stage, can be unilateral or bilateral, and is of multifactorial cause, including those patients associated with the use of medications, where an imbalance in the testosterone ­ estrogen ratio. Relatively, idiopathic is the most common. Most regress spontaneously, neonatals due to loss of transplacental influx in the first weeks, and pubertal ones between 12 to 24 months. It presents as an increase in breast size, asymptomatic or with hypersensitivity due to inflammation during the growth of the mammary fibroglandular tissue, with an enormous psychological repercussion, especially in adolescence. The study and management is interdisciplinary and offered according to conditions and etiology. Those pubertal patients in whom it does not regress receive medical treatments, or surgical treatments when therapy fails or there is social pressure, and even radiotherapy in cases where they develop gynecomastia with hypersensitivity to hormonal treatment of prostate cancer

RESUMO

La ginecomastia es el crecimiento mamario benigno en el varón. Etiológicamente se clasifica en fisiológica y patológica. La ginecomastia fisiológica se presenta frecuentemente en ciertos periodos de la vida, como la época neonatal, puberal y senil. La patológica se asocia a múltiples factores, incluyendo los hormonales, los de origen tumoral, y al uso de ciertos medicamentos, entre otros; sin embargo, en muchos pacientes no se consigue identificar nunca la causa. La historia clínica y el examen físico son los pilares fundamentales que permiten orientar hacia la etiología, con el apoyo de pruebas de laboratorio e imagenología que permitan descartar una enfermedad clínica subyacente. En los casos moderados o severos, la cirugía es el tratamiento de elección. El objetivo del presente manuscrito es discutir algunos puntos de interés acerca de los aspectos más importantes relacionados con la ginecomastia, incluyendo la fisiopatología, la clínica y el diagnóstico, además de presentar las principales causas asociadas a esta condición. Por último, se describen los tipos de tratamiento disponibles para estos pacientes

Gynecomastia is the benign breast enlargement in males. Etiologically it is classified as physiological and pathological. Physiological gynecomastia is more frequently observed in newborns, adolescents, and in older men. Pathological gynecomastia is associated with multiple factors, including hormonal and of tumor origin, and to the use of certain medications, among other factors; however, in many patients the underlying cause may never be identified. Anamnesis and physical examination are the fundamental pillars that will guide towards the etiology, with the support of laboratory and imaging tests to rule out an underlying disease. In moderate or severe cases, surgery is the treatment of choice. The aim of this article is to discuss some key points about the most important aspects related to gynecomastia, including pathophysiology, symptoms and diagnosis, in addition to presenting the main causes associated with this condition. Finally, the types of treatment available for these patients are described

RESUMO

Introduction: Gynecomastia (GM) is a benign proliferation of glandular breast tissue in men. Some cases need surgical intervention. Traditional open surgery by semicircular inferior periareolar incision is the most common surgical approach. In order to obtain better esthetic results, some alternatives to open surgery have been proposed, such as liposuction, endoscopic mastectomy, and vacuum-assisted excision (VAE). Objective: To describe the technical surgical approach of ultrasound-guided VAE of GM and its results from a case series. Method: This is an evaluation of seven GM cases submitted to ultrasound-guided VAE with a 10G needle using the ENCOR® BD whole circumference automated breast biopsy system in Redimasto ­ Redimama, a Brazilian breast center. The result was considered good or satisfactory when it showed minimal remaining gland, good symmetry, no retraction, necrosis, hypertrophic scar, or displacement of the nipple-areola complex. All patients answered a questionnaire to evaluate their satisfaction and perception of the procedure. Results: Seven (7) patients with Simon grade 1 and 2 bilateral GM underwent ultrasound-guided VAE. No case of displacement, necrosis, or retraction of the nipple-areola complex, post-procedure bleeding, infection, skin necrosis, or asymmetry was detected. No patient reported decrease or change in nipple sensation or erection. All patients had bruises and hematomas that spontaneously resolved within 30 days. All results were considered good or excellent by patients and surgeons. Conclusion: Minimally invasive ultrasound-guided VAE is an excellent alternative for the treatment of GM. It is better indicated for Simon grade 1 and 2 GM, with good and excellent esthetic results, small scar, and low rates of nipple and areolar complications. It allows an outpatient procedure with low morbidity (local anesthesia) and fast recovery.

RESUMO

ABSTRACT Objective: To present a case of bilateral gynecomastia in a prepubertal boy with autism spectrum disorder, diagnosed with myotonic dystrophy type 1. Case description: A 12-year-old boy with autism spectrum disorder presented at a follow-up visit with bilateral breast growth. There was a family history of gynecomastia, cataracts at a young age, puberty delay, and myotonic dystrophy type 1. The physical examination showed that he had bilateral gynecomastia with external genitalia Tanner stage 1. Neurologic examination was regular, without demonstrable myotonia. The analytical study revealed increased estradiol levels and estradiol/testosterone ratio. After excluding endocrine diseases, the molecular study of the dystrophia myotonica protein kinase gene confirmed the diagnosis of myotonic dystrophy type 1. Comments: A diagnosis of prepubertal gynecomastia should include an investigation for possible underlying diseases. This case report highlights the importance of considering the diagnosis of myotonic dystrophy type 1 in the presence of endocrine and neurodevelopmental manifestations.

RESUMO Objetivo: Apresentar o caso de um adolescente pré-púbere com ginecomastia bilateral e transtorno do espectro autista, diagnosticado com distrofia miotônica tipo 1. Descrição do caso: Adolescente do sexo masculino de 12 anos, com transtorno do espectro autista, observado em consulta de seguimento por crescimento mamário bilateral. O paciente tinha antecedentes familiares de ginecomastia, catarata em idade jovem, atraso pubertário e distrofia miotônica tipo 1. À observação física, apresentava ginecomastia bilateral estádio 1 de Tanner. O exame neurológico era normal, sem miotonia aparente. O estudo analítico mostrou níveis elevados de estradiol e da relação estradiol/testosterona. Após exclusão de causas endócrinas, o estudo molecular do gene DMPK confirmou o diagnóstico de distrofia miotônica tipo 1. Comentários: Perante um quadro de ginecomastia pré-púbere, deve-se excluir doenças subjacentes. Este caso reforça a importância de considerar o diagnóstico de distrofia miotônica tipo 1 na presença de manifestações endócrinas e do neurodesenvolvimento.

RESUMO

Introducción: La ginecomastia es una patología benigna frecuente pero muy poco estudiada, caracterizada por el desarrollo de la mama en el hombre dándole una apariencia femenina, lo que puede ocasionar estrés emocional y a su vez retrasa o evita que el paciente acuda a consulta médica especializada. Debido a que no se acompaña de signos de malignidad, la mayoría de médicos generales sólo la consideran una alteración estética; sin embar-go, el tratamiento quirúrgico de fácil realización ayuda al paciente a restaurar su autoestima.Presentación de casos: Durante el periodo febrero ­ noviembre del 2019 se presentaron ocho casos de gineco-mastia que corresponde a la cuarta causa más frecuente de procedimientos quirúrgicos en el Hospital General Quevedo IESS. La edad de los pacientes se ubicó entre 17 y 30 años. El tratamiento quirúrgico de elección fue mastectomía subcutánea. El promedio de estancia hospitalaria fue de 1.3 días, el tiempo de retiro de drenaje as-pirativo fue entre el tercer y quinto día y la complicación quirúrgica más frecuente (50%) fue el seroma.Conclusiones: Esta serie de casos demuestra la importancia del diagnóstico de la ginecomastia, del tratamiento quirúrgico subcutáneo y el cuidado post-quirúrgico para lograr equilibrio biopsicosocial del individuo. Aunque hace falta más evidencia, en lo posible se debería realizar mastectomías subcutáneas que carecen de complica-ciones quirúrgicas graves.

Background: Gynecomastia is a common but little studied benign pathology, characterized by the development of the breast in men giving it a feminine appearance, which can cause emotional stress and in turn delays or prevents the patient from going to a specialized medical consultation. Because it is not accompanied by signs of malignancy, most general practitioners consider it only an aesthetic alteration; however, the easy-to-perform surgical treatment helps the patient restore self-esteem.Cases presentation: Case series: During the period February - November 2019, there were 8 cases of gynecomas-tia, which corresponds to the fourth most frequent cause of surgical procedures at the General Hospital of Quevedo IESS. The age of the patients was between 17 and 30 years. The surgical treatment of choice was subcutaneous mastectomy. The mean hospital stay was 1.3 days, the suction drain removal time was between the third and fifth day, and the most frequent surgical complication (50%) was seroma. Conclusions: This series of cases demonstrates the importance of gynecomastia diagnosis, subcutaneous surgi-cal treatment and post-surgical care to achieve bio-psycho-social balance of the individual. Although more eviden-ce is needed, subcutaneous mastectomies that lack serious surgical complications should be performed whenever possible.

RESUMO

Breast benign tumors, intraductal papilloma and fibroadenomas are common conditions in women; however, they are very rare in males. In this study, we report the case of a male patient, 75 years old, presenting with complaint of bilateral gynecomastia and palpable retroareolar mass in the left breast. The patient was submitted to imaging tests and core biopsy, and the hypothesis of intraductal papilloma was confirmed upon anatomopathological study. The mastology team opted for excision of the lesion and correction of gynecomastia.

Tumores benignos da mama, papiloma intraductal e fibroadenomas são condições comuns em mulheres, mas muito raras em homens. Neste estudo, relatamos o caso de um paciente do sexo masculino, com 75 anos de idade, cuja queixa era de ginecomastia bilateral e massa retroareolar palpável na mama esquerda. O paciente foi submetido a exames de imagem e core-biopsy, e a hipótese de papiloma intraductal foi confirmada após estudo anatomopatológico. A equipe de mastologia optou pela excisão da lesão e correção da ginecomastia.

RESUMO

Transsexual individuals with gender dysphoria or gender identity disorder are rare, with a prevalence reported to range from 0.002% to 0.014%. Studies have shown that mastectomy yields significant improvements in body image and self-esteem in female-to-male transsexual patients. In patients with grade III breast ptosis, mastectomy with a nipple-areolar complex (NAC) graft is the most commonly used technique, although it has several disadvantages. In the case described herein, a bilateral mastectomy preserving the NAC in an inferior pedicle was performed. Additionally, a thin superior thoracic dermal-fat flap was preserved and eventually sutured at the previous inframammary fold, preventing an inverted T scar. This case shows the advantage of this technique for preserving the blood supply and innervation of the NAC, with a low hypopigmentation risk. Furthermore, in this technique, the patch effect does not impair the results of the NAC graft, and there is no need to use an inverted T scar that may result in thoracic feminization.

RESUMO

La ginecomastia es el crecimiento de la mama por un desequilibrio hormonal entre estrógenos y andrógenos. Un crecimiento importante y unilateral requiere descartar patologías subyacentes. Una causa poco frecuente es la traumática, que provoca aumento de tamaño por estimulación repetida. Se presenta el caso de un niño de 6 años con ginecomastia unilateral. Se destaca como único hallazgo en las pruebas complementarias hiperprolactinemia. Rehistoriando, se detecta una continua autoestimulación mamaria manual y oral a través de mordiscos de meses de evolución. Tras el cese del estímulo, se observa la involución de la mama y la normalización de los niveles de prolactina séricos.

Gynecomastia consists of breast enlargement due to a hormonal imbalance between estrogens and androgens. Unilateral and important breast growth requires ruling underlying pathologic disorders out. Mechanical cause is uncommon, causing enlargement by repeated stimulation. We report a 6-year-old boy with unilateral gynecomastia. Hyperprolactinemia is the only abnormal finding at laboratory tests. After repeated inquiries, a continuous breast selfstimulation is detected. Its relation with gynecomastia is verified because prolactin normalizes and breast regressed in further revisions, after stopping stimulus.

RESUMO

INTRODUCTION: Aesthetic breast area improvements for gynecomastia and gender dysphoria patients who seek a more masculine appearance have increased recently. We present our clinical experience in breast masculinization and a classification for these patients. METHODS AND MATERIALS: From July 2003 to May 2014, 68 patients seeking a more masculine thorax underwent surgery. They were divided into five groups depending on three factors: excess fatty tissue, breast tissue, and skin. A specific surgical treatment was assigned according to each group. The surgical treatments included thoracic liposuction, subcutaneous mastectomy, periareolar skin resection in one or two stages, and mastectomy with a nipple areola complex graft. The evaluation was performed 6 months after surgery to determine the degree of satisfaction and presence of complications. RESULTS: Surgery was performed on a total of 68 patients, 45 male and 22 female, with ages ranging from 18 to 49 years, and an average age of 33 years. Liposuction alone was performed on five patients; subcutaneous mastectomy was performed on eight patients; subcutaneous mastectomy combined with liposuction was performed on 27 patients; periareolar skin resection was performed on 11 patients; and mastectomy with NAC free grafts was performed on 16 patients. The surgical procedure satisfied 94% of the patients, with very few complications. CONCLUSIONS: All patients who wish to obtain a masculine breast shape should be treated with only one objective regardless patient's gender: to obtain a masculine thorax. We recommend a simple mammary gland classification for determining the best surgical treatment for these patients LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.

RESUMO

Introducción: La ginecomastia define el aumento benigno del tamaño de la glándula mamaria en el hombre. Existen diversos abordajes quirúrgicos para la resección de la lesión, cada una con resultados diferentes. Material y métodos; Estudio transversal. Se incluyeron pacientes con ginecomastia operados de mastectomía subdérmica mediante incisión periareolar externa e incisión periareolar inferior. Para la aleatorización se tomó en cuenta los grados IIb y III de Simon, distribuyendo uno a uno para cada tipo de incisión. Los resultados estéticos fueron evaluados por un cirujano experimentado, tomando como excelentes cuando hubo una cicatrización correcta sin deformidad del área, buenos cuando la cicatrización fue buena sin deformidad del área y mala cuando hubo deformidad del área operada. Resultados: Fueron operados 24 pacientes, el 50% por incisión periareolar externa y el 50% por incisión periareolar inferior. La edad promedio fue 25,58 y 27,58 años respectivamente, sin diferencias significativas p = 0,513. Todos los pacientes tuvieron características sexuales secundarias normales. La etiología fue idiopática en 23 pacientes (95,83%). El tiempo promedio de evolución fue 32,28 meses y en todos el resultado histopatológico fue ginecomastia. La evaluación del aspecto estético de la incisión y el área afectada en los pacientes operados mediante incisión periareolar externa (n = 12) fue mala en un paciente (8,33%), buena en 2 (16,66%) y excelente en 9 pacientes (75%), mientras que en los pacientes operados mediante incisión periareolar inferior, fue buena en el 100% de los pacientes, y mala y excelente en ningún paciente, con diferencias estadísticamente significativas para ambas incisiones, p = 0,000. Ningún paciente presentó complicaciones. Conclusión: Ambas incisiones son seguras.

RESUMO

Se presentó la evolución de un paciente con pseudoginecomastia tratado en el Servicio de Cirugía Plástica del Hospital Vladimir Ilich Lenin durante diciembre de 2013. Se le realizaron estudios hormonales que arrojaron resultados dentro de límites normales y ultrasonido donde se informó predominio de tejido graso. Acudió a consulta psicológicamente afectado por la apariencia femenina de sus mamilas y se decidió tratamiento quirúrgico. Se combinaron ambas técnicas quirúrgicas, primero se aspiró la grasa periareolar en exceso y luego se cortó la piel redundante alrededor de las areolas de formas periareolar; con lo que se logró una aproximación estética a la apariencia masculina de sus mamilas después de una intervención quirúrgica, combinando la lipoaspiración con la técnica periareolar para minimizar las cicatrices que denotarían una mamila operada.

The evolution of a patient with pseudoginecomastia treated in the Plastic Surgery of Vladimir Ilich Lenin Hospital in December 2013 was presented. The results of hormonal studies were normal and ultrasound showed predominance of fatty tissue. The patient was psychologically affected because his breast looked like the female one. Surgical treatment was decided to perform. Two surgical techniques were combined, the first one was the periareolar fat aspiration and the second one was to cut the redundant skin around the areola; obtaining a male aesthetic appearance trying to minimize scarring.

RESUMO

La ginecomastia es una entidad de consulta frecuente, definida por la proliferación del tejido glandular mamario en los hombres, en la mayoría de los casos benigna y se puede presentar a cualquier edad. Debido a su etología variada y repercusiones tanto físicas como emocionales, debe realizarse un abordaje completo para descartar causas patológicas y realizar un tratamiento dirigido en los casos que lo ameritan.

Gynecomastia is a common condition defined as the proliferation of male breast glandular tissue. It is benign in most cases and it can appear at any age. Due to its distinct etiology and physical/psychologic outcomes, a complete approach must be performed to rule out pathologic causes, and to offer precise treatment.
