RESUMO

Objective: To evaluate a not yet described ultrasound finding, the dilation of the intra-papillary portion of the lactiferous duct in patients with or without abnormal nipple discharge Methods: 24 patients with pathological nipple discharge and intrapapillary duct dilation and 1,255 asymptomatic patients (control group) were studied. Results: Just one asymptomatic patient had intrapapillary duct dilation. Among the symptomatic patients, 19 were biopsied: ten with exclusively percutaneous approach, six with exclusively surgical approach, and three with an initial percutaneous and then a surgical approach. There was one invasive carcinoma and two carcinomas in situ (15.8% of the biopsied patients). In 11 patients, a papilloma was found, three of them with atypia. In one patient, ultrasonography identified intrapapillary extension of microcalcifications, and another patient a changed duct diametrically opposite to the duct which had a trigger point. In these two patients, the examination changed the treatment strategy. In two other patients, an extra-papillary finding was identified only after the intrapapillary duct dilation has been encountered. Conclusion: The intrapapillary duct dilation is a new ultrasonography sign that adds sensitivity to the evaluation of the patient with pathological nipple discharge, besides helping to find the lesion and to guide the treatment. Further research is needed to determine its prevalence and its positive and negative predictive values for cancer, atypia and papilloma

Objetivo: Avaliar um achado de ultrassonografia inédito (dilatação intrapapilar do duto lactífero) em pacientes portadoras de fluxo papilar patológico e em pacientes assintomáticas. Métodos: Foram estudadas 24 portadoras de fluxo papilar patológico e dilatação ductal intrapapilar e 1.255 pacientes assintomáticas (grupo controle). Resultados: Apenas uma paciente assintomática apresentou dilatação ductal intrapapilar. Entre as pacientes sintomáticas, 19 foram biopsiadas, 10 com abordagem exclusivamente percutânea, 6 com abordagem exclusivamente cirúrgica e 3 com abordagem inicialmente percutânea e depois cirúrgica. Houve um carcinoma invasor e dois carcinomas in situ (15,8% das pacientes biopsiadas). Em 11 pacientes foi encontrado papiloma, 3 deles com atipias. Em uma paciente a ultrassonografia identificou extensão intrapapilar de microcalcificações e em outra, um duto alterado diametralmente oposto ao duto com sinal do gatilho clínico. Nessas duas pacientes o exame mudou a estratégia de tratamento. Em duas pacientes, um achado extrapapilar só foi identificado após o encontro da dilatação ductal intrapapilar. Conclusão: A dilatação ductal intrapapilar é novo sinal ultrassonográfico que agrega sensibilidade à avaliação da paciente com fluxo papilar patológico, além de ajudar a encontrar a lesão e a orientar o tratamento. São necessárias pesquisas adicionais para determinar sua prevalência e seus valores preditivos positivo e negativo para câncer, atipias e papilomas.

RESUMO

Abstract Nipple discharge is a common symptom in clinical practice, representing the third leading breast complaint, after pain and lumps. It is usually limited and has a benign etiology. The risk of malignancy is higher when the discharge is uniductal, unilateral, spontaneous, persistent, bloody, or serous, as well as when it is accompanied by a breast mass. The most common causes of pathologic nipple discharge are papilloma and ductal ectasia. However, there is a 5% risk of malignancy, mainly ductal carcinoma in situ. The clinical examination is an essential part of the patient evaluation, allowing benign nipple discharge to be distinguished from suspicious nipple discharge, which calls for imaging. Mammography and ultrasound should be used together as first-line imaging methods. However, mammography has low sensitivity in cases of nipple discharge, because, typically, the lesions are small, are retroareolar, and contain no calcifications. Because the reported sensitivity and specificity of ultrasound, it is important to use the correct technique to search for intraductal lesions in the retroareolar region. Recent studies recommend the use of magnetic resonance imaging in cases of suspicious nipple discharge in which the mammography and ultrasound findings are normal. The most common magnetic resonance imaging finding is non-mass enhancement. Surgery is no longer the only solution for patients with suspicious nipple discharge, because short-time follow-up can be safely proposed.

Resumo O derrame papilar é um sintoma frequente na prática clínica, correspondendo à terceira queixa mais comum, sendo precedido apenas por dor e massas palpáveis. A maioria dos derrames papilares é de origem benigna e transitória, sendo definidos como derrames papilares patológicos os que se apresentam uni ou pauciorificiais, espontâneos, persistentes, serosos ou sanguinolentos e associados a alteração palpável. Os derrames patológicos são mais frequentemente causados por papiloma ou ectasia ductal, porém, existe risco de malignidade de cerca de 5%, constituído principalmente por carcinoma ductal in situ. O exame clínico é parte essencial na avaliação da paciente, permitindo diferenciar entre derrames papilares tipicamente benignos e derrames papilares suspeitos, que necessitam de avaliação pelos métodos de imagem. A mamografia e a ultrassonografia devem ser usadas em conjunto como métodos de imagem de primeira linha, porém, a sensibilidade da mamografia nestes casos é baixa, uma vez que as lesões são comumente retroareolares, pequenas e não calcificadas. A sensibilidade e a especificidade da ultrassonografia variam amplamente na literatura, sendo importante o uso de técnicas corretas para a avaliação de lesões intraductais e retroareolares. Recentemente, a ressonância magnética tem sido indicada nos casos de derrame papilar suspeito com mamografia e ultrassonografia normais, sendo o achado mais comum o realce não nodular. A cirurgia não é mais a única solução para as pacientes com derrame papilar suspeito e todos os exames de imagem normais, tendo em vista que um seguimento em curto prazo pode ser proposto de forma segura.

RESUMO

INTRODUCTION: Bloody nipple discharge is an infrequent symptom during childhood. The most common cause in this population is mammary duct ectasia (MDE), which is a benign and self-limiting condition, that is characterized by dilatation of the mammary ducts, fibrosis and periductal inflammation. OBJECTIVE: Report of a case of MDE in order to improve physicians' diagnosis accuracy and avoid aggressive studies and treatments. CASE REPORT: Six-months old male healthy infant, exclusively breastfeeded, that visited our clinic with a lump beneath his right nipple and bloody discharge from the same nipple. An ultrasound was performed which showed a multicystic lesion suggestive of MDE. Watchful waiting was decided as treatment, with good evolution after six months of follow up. CONCLUSIONS: The MDE is the leading cause of bloody discharge in pediatric population, being a benign condition that resolves spontaneously before nine months. The knowledge of this condition is essential so as to accurately diagnose and treat it.

RESUMO

Introducción: La telorragia es un síntoma poco frecuente en pacientes pediátricos, la causa más frecuente en esta población es la ectasia ductal mamaria (EDM), que es una afección benigna y autolimitada, caracterizada por la dilatación del conducto mamario, fibrosis e inflamación periductal. Objetivo: Presentar un caso de EDM, para facilitar el rápido reconocimiento por parte de los médicos, y evitar estudios y tratamientos agresivos. Caso clínico: Lactante de sexo masculino de 6 meses de edad, sano, alimentado por lactancia materna exclusiva; consultó por un nódulo retroareolar derecho y telorragia unilateral. Se realizó una ecografía Doppler que mostró una lesión multiquística, sugerente de una EDM. Se planteó tratamiento expectante y acudió a control a los 6 meses con excelente evolución. Conclusiones: La EDM es la principal causa de telorragia en niños, corresponde a una afección benigna, y la resolución generalmente es espontánea, antes de los 9 meses. Por lo que su conocimiento es de gran relevancia para el adecuado diagnóstico y manejo de estos pacientes.

RESUMO

La descarga de sangre a través del pezón (telorragia) es un síntoma muy infrecuente en pediatría. Si bien genera gran preocupación y alarma por su equivocada asociación con el carcinoma de pacientes adultos, en los niños se asocia, en la mayoría de los casos, con una ectasia ductal benigna. Hasta el momento, sólo existen informes o series de casos y, aunque se proponen diferentes teorías, la causa no se conoce con exactitud. Se presentan dos casos con características clínicas y evolución muy similar, en los que el sangrado se resolvió en forma espontánea, uno en cuatro y el otro en seis semanas. Se realiza una revisión del tema y, dado que se trata de un proceso benigno y autolimitado, se sugiere, en ausencia de otros hallazgos en el examen físico, realizar estudios mínimamente invasivos, adoptar una conducta expectante y tranquilizar a la familia en la espera de una resolución espontánea.(AU)

Bloody discharge from the nipple (thelorrhagia) is a rare symptom in childhood and is a cause of great concern due to the mistaken association with carcinoma in adults. However, in children thelorrhagia is due to benign mammary duct ectasia in the majority of cases. Up to date, only isolated case reports or case series have been published and, although different theories have been postulated, no definite etiology has been identified. We report two cases with similar clinical features and outcome, in whom bleeding resolved spontaneously 4 and 6 weeks after onset. We present a review of the literature. Based on the benign and self-limiting process and in the absence of other findings on physical examination, we suggest a watch-and-wait approach with minimally invasive studies and reassurance and support for the family as most cases resolve spontaneously.(AU)

RESUMO

A pesar de constituir la ectasia ductal la causa que con mayor frecuencia ocasiona sangrado a través del pezón en neonatos y lactantes, por la rareza de esta entidad, no deja de sorprender y agobiar a quienes la constatan. Se presenta un lactante masculino, de 8 semanas de nacido, cuyos padres acuden a la Consulta de Endocrinología por sangrado por ambos pezones. Ambas mamas, areolas y pezones mostraban características normales, solamente se halló sangrado con la presión, y el resto del examen físico no mostró alteraciones. La ecografía mamaria fue normal y el estudio citológico confirmó el diagnóstico de ectasia ductal primaria. En el paciente el sangrado cedió espontáneamente con resolución completa en varias semanas. Actualmente, con 3años y 8 meses de edad, no ha presentado nuevas manifestaciones. Por la rareza de su presentación en recién nacidos y lactantes, son muy escasos los informes de esta entidad en la literatura médica, y hasta el momento no hemos encontrado otras descripciones de esta infrecuente enfermedad en artículos nacionales cubanos, lo que motivó la presentación de este caso clínico(AU)

Despite the fact that duct ectasia is the most common cause of bloody nipple discharge in neonates and infants, this rare entity still surprises and causes stress on those who observe it. A male 8 weeks-old patient was presented. His parents took him to the endocrinology service because his two nipples were bleeding. His breasts, areolae, and nipples showed normal characteristics, just bleeding when squeezed; the physical exam did not show any alteration. The breast echography was normal and the cytological study confirmed the diagnosis of primary duct ectasia. The bleeding ceased spontaneously and he completely recovered after several weeks. At present, the patient is 3 years and 8 months-old and does not show any new manifestation. Due to the rareness of this illness in neonates and infants, data are very incomplete in medical literature. Other descriptions of this uncommon disease have not been found in the Cuban national literature, so this encouraged us to present this clinical case(AU)

RESUMO

A descarga papilar está presente em 5% das mulheres e ocorre em razão de causas fisiológicas, doenças benignas da mama e câncer de mama. Algumas das lesões benignas da mama estão relacionadas a um maior risco de desenvolvimento de patologia maligna mamária. A papilar para a avaliação desse sintoma mamário e sua relação com as lesões benignas importância da descarga papilar está na possibilidade de essa condição associar-se a câncer de mama. Uma avaliação clínica detalhada é fundamental para a determinação da abordagem terapêutica da paciente com descarga papilar. Foram avaliadas 23 pacientes do Serviço de Mastologia do Instituto Fernandes Figueira/Fiocruz submetidas à exérese de árvore ductal em virtude de descarga e com o câncer de mama. Das 23 pacientes analisadas, o resultado histopatológico foi de lesão benigna não proliferativa em 26,1%, lesão proliferativa sem atipias em 60,8%, hiperplasia ductal com atipias em 8,7% e câncer em 4,4%. Os resultados demonstraram que em 69,5% dos casos a histopatologia foi de lesão proliferativa de mama, que, apesar de benigna, apresenta maior risco de desenvolvimento do câncer de mama. Apesar de a descarga papilar estar na maioria dos casos relacionada à doença mamária benigna, em alguns casos esta se associa a um risco aumentado de câncer de mama. É fundamental ressaltar que pode haver uma relação entre a descarga papilar e o câncer de mama, embora este não seja a correspondência histopatológica mais freqüente da descarga papilar.

Nipple discharge is present in 5% of women and occurs due to physiological causes, benign breast disease and breast cancer. Some of benign breast lesions are associated with a higher risk of malignant breast diseases development. The importance of nipple discharge is the possibility of this condition to be associate with breast cancer. A detailed clinical evaluation is fundamental to determinate the therapeutic approach of a patient with nipple discharge. Twenthy-three patients from the Mastology Department of Fernandes Figueira Institute/Fiocruz were submitted to removal of central mammary ducts due to nipple discharge for evaluation of this symptom and its relationship with benign breast lesions and breast cancer. The histopathological results from 23 patients that have been analysed were not proliferative benign breast lesions in 26.1%, proliferative lesions without atypias in 60.8%, atypical ductal hyperplasia in 8.7% and 4 cancer in 4,4%. The results proved 69.5% of proliferative breast lesions thats presents a higher risk of breast cancer development. Although nipple discharge is associated in most of the cases with benign breast diseases sometime it is related to a higher risk of breast cancer. It is important to emphasize that it could be a relation between nipple discharge and breast cancer even if it is not the most frequent, histopathological correspondence of nipple discharge.
