RESUMO

Los mucoceles son lesiones de extravasación salival asociados a la ruptura de los conductos que generalmente se asocian con trauma. Son azuláceos, con aspecto traslúcido, fluctuantes a la palpación, expansivos y de crecimiento rápido. Mayoritariamente se manifiestan en población joven. El sitio más común de localización es la mucosa de labio inferior, sin embargo, pueden presentarse en cualquier zona que contenga glándulas salivales menores, como vientre de lengua, donde se encuentran las glándulas Blandin-Nuhn. La frecuencia de las lesiones asociadas a éstas glándulas es del 2.25% reportándose aproximadamente 400 casos hasta la fecha. La finalidad de ésta publicación es la descripción de una patología infrecuente, así como realizar una revisión a la literatura. Se presenta el caso de una niña de tres años con historia de aumento de volumen congénito en el dorso de la lengua sin síntomas compatibles con mucocele, se realiza biopsia excisional bajo anestesia general. El resultado del estudio histopatológico reporta: fenómeno de extravasación de mucosa. Paciente evoluciona satisfactoriamente. Estas lesiones expansivas pueden repercutir en el desenvolvimiento normal de la vida de las personas causando dislalia, disfagia y disnea. El tratamiento de este tipo de lesiones en la infancia favorece a un adecuado desarrollo del habla y mejora las condiciones de alimentación.

Mucoceles are salivary extravasation lesions associated with rupture of ducts that are generally associated with trauma. They are bluish, translucent in appearance, fluctuating on palpation, expansive and fast growing. They mostly occur in young people. The most common site of location is the mucosa of the lower lip, however, they can occur in any area that contains minor salivary glands, such as the belly of the tongue, where the Blandin-Nuhn glands are located. The frequency of lesions associated with Blandin-Nuhn's glands is 2.25%, with approximately 400 cases reported to date. The purpose of this publication is the description of an uncommon pathology, as well as a review of the literature. The case of a three-year-old female with a history of congenital volume increase at the dorsum of the tongue without symptoms compatible with mucocele is reported, an excisional biopsy was performed under general anesthesia. The result of the histopathological study reports: extravasation mucus phenomenon. Patient evolves satisfactorily. These expansive lesions can affect the normal development of people's lives, causing dyslalia, dysphagia and dyspnea. Treatment of this type of injuries in childhood favors adequate speech development and improves feeding conditions.

RESUMO

Sialolithiasis is a common nonneoplastic disease of the major salivary glands that often affects the submandibular glands. Minor salivary gland involvement by sialolithiasis is uncommon, with only 273 cases reported. A long clinical history, acute symptoms, and mucopurulent discharge are unusual features of these cases. Herein, we report the case of a 63-year-old woman who complained of symptomatic nodular swelling of the buccal mucosa associated with purulent discharge for several days. The clinical history lasted 15 years, with episodes of asymptomatic non-suppurative swelling in the same area. The patient underwent surgical excision. The microscopic examination revealed chronic nonspecific sialadenitis associated with psammomatous calcifications, confirming minor salivary gland sialolithiasis. After 3 years of follow-up, the patient was free of symptoms. Patients with sialolithiasis are usually asymptomatic; however, swelling, pain, and fistula may be present in rare cases. The presence of purulent exudate should lead to the differential diagnosis of stomatitis glandularis, a rare inflammatory condition affecting the minor salivary glands. Sialolithiasis and stomatitis glandularis should be considered in the clinical differential diagnosis of symptomatic suppurative nodular swelling affecting the oral mucosa, and histopathological analysis is necessary for the diagnosis.

RESUMO

ABSTRACT Mammary analogue secretory carcinoma is a rare neoplasm usually confused with other neoplasms in the salivary glands region. It has great similarity with the breast carcinoma. We report a case of a patient who presented with gingival submucosal bleeding and lesion, with the initial histopathological examination revealing salivary gland neoplasm of low crane. Computed tomography revealed the lesion near the tooth 27, with extension to the floor of the left maxillary sinus and to the palate mucosa. Resection of the infra-structure was performed, with a diagnosis of breast cancer secretory carcinoma in the minor salivary gland.

RESUMO

Pleomorphic Adenoma (PA) is the most common benign salivary gland tumor. The most common sites for minor salivary gland from which PA arises are the palate followed by the lips and buccal mucosa. Calcifications are a common finding in major salivary glands with chronic inflammatory disorders. Major salivary gland tumors rarely show calcifications and it is less common to find them in minor salivary gland tumors. We report a case of pleomorphic adenoma of the hard palate in a 67-year-old female patient with intra-tumoral, irregular and scattered calcifications visible on computed tomography (CT). The treatment was complete surgical excision of the lesion. The diagnosis was confirmed with the histopathological study.

El adenoma pleomórfico (AP) es el tumor benigno de las glándulas salivales más común. Los sitios de mayor frecuencia donde surge el AP en glándulas salivales menores es el paladar seguido de los labios y la mucosa bucal. Las calcificaciones son un hallazgo común en las glándulas salivales mayores con trastornos inflamatorios crónicos, pero en el caso de tumores rara vez muestran calcificaciones y es menos común encontrarlos en tumores de las glándulas salivales menores. Presentamos un caso de adenoma pleomórfico del paladar duro en una paciente de 67 años con calcificaciones intratumorales, irregulares y dispersas visibles en la tomografía computarizada. El tratamiento fue la extirpación quirúrgica completa de la lesión. El diagnóstico se confirmó con el estudio histopatológico

RESUMO

RESUMEN El adenoma canalicular (AC) es una neoplasia epitelial benigna infrecuente de las glándulas salivales menores localizada principalmente en el labio superior. Se manifiesta como un nódulo menor de 3 centímetros, indoloro, no ulcerado y de crecimiento lento. El diagnóstico diferencial se debe hacer con otros tumores de las glándulas salivales como adenoma de células basales, adenoma pleomórfico y carcinoma adenoide quístico. Se presenta el caso de una paciente con antecedente de adenoma canalicular en el labio superior extirpado 13 años antes, que consultó en junio de 2015 por una lesión de 8 mm de diámetro en la misma localización. En septiembre del mismo año se resecó la lesión, incluyendo la glándula salival accesoria adyacente. El estudio histopatológico confirmó nuevamente el diagnóstico de AC y mostró multifocalidad del tumor en la glándula salival accesoria.

SUMMARY Canalicular adenoma is an unusual benign epithelial neoplasm of the minor salivary glands located primarily on the upper lip. It appears as a slowgrowing node, less than 3 cm in diameter, painless, and non-ulcerated. Differential diagnosis should be made with other tumors of the salivary glands such as basal cell adenoma, pleomorphic adenoma and adenoid cystic carcinoma. We report the case of a female with a history of canalicular adenoma (CA) on the upper lip, removed 13 years before, who consulted on June 2015 because of a mass, 8 mm in diameter with the same location as the previous lesion. On September 2015, the lesion and the accessory salivary gland were removed. Histopathological study found the same diagnosis as before (CA), and revealed multifocality of the neoplasm in the accessory salivary gland.

RESUMO

ABSTRACT Objective To evaluate the clinical-pathological profile of patients with minor salivary gland neoplasms. Methods A retrospective study of specific cases diagnosed as benign and malignant tumors of the minor salivary glands was performed. The data were collected from medical records of patients seen at a hospital over a period of 15 years. The sample was made up of 37 cases. For the pathological study, slides containing 5μm thick sections stained with hematoxylin and eosin were used. The data were tabulated using descriptive statistics. Results Malignant neoplasms represented 70.3% of cases. The mucoepidermoid carcinoma was the most common neoplasm (45.9%), followed by pleomorphic adenoma (24.4%). Most patients were female (70.3%), aged between 71 and 80 years. The palate (67.6%) and the retromolar region (10.8%) were the most affected sites. Conclusion Mucoepidermoid carcinoma was the most common tumor in minor salivary glands. These tumors are more common in females aged over 40 years. The palate was the most common affected site.

RESUMO Objetivo Avaliar o perfil clínico-patológico de pacientes com neoplasias de glândula salivar menor. Métodos Foi realizado um estudo retrospectivo de casos específicos diagnosticados como neoplasias benignas ou malignas de glândula salivar menor. Os dados foram coletados dos prontuários dos pacientes atendidos em um hospital no período de 15 anos. A amostra final foi de 37 casos.

RESUMO

INTRODUCTION: Cystadenoma is an uncommon epithelial neoplasia that arises from the salivary glands. The malignancy can affect structures such as the larynx, nasopharynx, buccal mucosa, and palate. OBJECTIVE: To describe a case of a giant cystadenoma of the floor of the mouth treated at a public hospital in midwestern Brazil. CASE REPORT: The patient was a 46-year-old woman with complaints of difficulties in articulating words and swallowing solid food and vocal fatigue. The progression of the disease since the initial consultation, the results of clinical examinations, and the outcome of surgery are described. FINALS COMMENTS: Cystadenoma must be considered in the differential diagnosis of cystic injuries in the floor of the mouth if the patient's symptoms are suggestive of this malignancy.

RESUMO

Trata-se de um relato de caso de Carcinoma Mucoepidermóide considerado um dos mais comuns tumores malignos das glândulas salivares. Usualmente tido como uma tumefação assintomática, especialmente no palato. O caso descrito ocorreu em paciente do sexo masculino, 37 anos, que compareceu a Clinica de Diagnóstico da Faculdade de Odontologia do Univag, queixando-se de um “caroço no céu da boca”, surgido há aproximadamente 5 anos. Ao exame físico intrabucal, observamos uma lesão nodular no palato duro, deslocada para o lado esquerdo, firme à palpação, recoberta por mucosa íntegra, com telangectasia, medindo aproximadamente 4 cm e exibindo formato ovalado e base séssil. O diagnóstico presuntivo foi Adenoma Pleomórfico. Após punção aspirativa e biópsia incisional foi estabelecido o diagnóstico de Carcinoma mucoepidermóide de glândulas salivares menores. O paciente foi tratado cirurgicamente por excisão completa que histopatologicamente confirmou as margens livres. Após 1 ano e 3 meses de acompanhamento, o paciente passa bem, sem recidiva da doença. Os autores alertam que diante de situação semelhante, com presença de tumefações de palato duro a hipótese diagnóstica de Carcinoma Mucoepidermóide deve ser considerada pelo clínico, ainda que o tempo de evolução seja longo, como no caso em questão

The Mucoepidermoid Carcinoma is one of the most common malignant tumor of salivary glands, and, usually, presents itself as an asymptomatic tumefaction, especially on the palate. Our study group presents a case on a 37-year-old male patient, who came to the Diagnostic Clinic Faculty of Dentistry at UNIVAG, complaining himself of a “node on the roof of mouth”, which had appeared about 5 years ago. Within the intra mouth physical exam, we noticed a lymph node on the hard palate, bent to the left side, consistent to the touch, covered by integral membrane, with telangectasia, measuring about 4 cm and showing oval formatted and sessile base. The presumptive diagnoses given was of Pleomorphic Adenoma. However after the aspiration punction and the incisional biopsy we had the diagnostic of Mucoepidermoid Carcinoma of minor salivary gland. The patient was surgically treated by complete excision that histopathologically confirmed the tumor-free margins. Therefore, the previous diagnostic hypothesis must be taken into consideration on dentists’ decision making, in view of tumefaction on hard palate, even if for long time of evolution, as the case here reported. After a year and three months following-up this case, the patient now is well and with no recidive of the disease
