Carcinoma ex pleomorphic adenoma of the sublingual gland: a case report / 国际口腔科学杂志·英文版

We report a case of carcinoma ex pleomorphic adenoma of a sublingual gland in a 70-year-old man. Under a clinical diagnosis of benign salivary gland tumor, excision of the mass with the sublingual salivary gland in an en bloc fashion via an intraoral approach was performed. Histopathologically, there was a rupture of the fibrous capsule and diffuse cell-rich sheets composed of myoepithelial cells with round nuclei were also seen. Immunohistochemically, the cells that composed of cell rich sheets were positive to smooth muscle actin. Final diagnosis of myoepithelial carcinoma ex pleomorphic adenoma was made.

Pleomorphic adenoma of the sublingual salivary gland: an unusual diagnostic challenge

To describe a rare case of pleomorphic adenoma of the sublingual gland. An 80-year-old patient presented with a painless solid submucosal mass of 4 months' duration in the anterior floor of the mouth, appearing as a distinct homogeneous, radiolucent lesion in CT imaging. Histologic findings after complete removal were suggestive of a pleomorphic adenoma almost completely surrounded by a fibrous capsule. No recurrence was observed after a 12-month follow-up. This case showed the possibility of sublingual salivary gland tumors and highlighted the need to consider them when making a differential diagnosis of masses located in the floor of the mouth

Quiste dermoide del suelo de la boca / Dermoid cyst in the mouth floor

El quiste dermoide representa menos del 0,01 por ciento de todos los quistes de la cavidad bucal. Su ubicación más frecuente es en suelo de boca. Se presenta el caso de una paciente femenina de 19 años de edad que hacía aproximadamente 7 años había notado un aumento de volumen debajo de la lengua, el cual le crecía paulatinamente y ya se apreciaba por fuera de la cara. Además, le ocasionaba molestias al hablar y al masticar. Se realizaron estudios complementarios y bajo anestesia general nasotraqueal. Se procedió a su exéresis quirúrgica mediante un abordaje intrabucal, donde se obtuvieron excelentes resultados estéticos y funcionales. El diagnóstico histopatológico se correspondió con un quiste dermoide de suelo de boca. La paciente no ha tenido recurrencia de la lesión transcurridos tres años de la operación. El quiste dermoide de suelo de boca se presenta como una tumoración benigna de la línea media. La exéresis intrabucal demuestra beneficios estéticos y funcionales(AU)

The Dermoid cyst account for the 0.01 percent of all cysts of buccal cavity. Its more frequent location is in the mouth floor. This is the case of a female patient aged 19 who approximately 7 years noted an increase of volume under tongue growing gradually and noting outside face and the discomfort at to speak and to chew. Complementary studies were conducted and under general anesthesia a surgical exeresis was carried out by intrabuccal approach achieving excellent esthetic and functional results. Histopathologic diagnosis matched with a dermoid cyst of mouth floor. Patient has not lesion recurrence after three years after operation. We conclude that the Dermoid cyst of mouth floor appear as benign tumor of middle line. The intrabuccal exeresis demonstrates esthetic and functional benefits(AU)

[ ten years epidemiologic study of salivary gland tumors in Loghman Hospital]

Salivary gland tumors are rarely reported comprising 2-3% of head and neck neoplasms. About 75% of salivary gland tumors are benign and 25%a are malignant. Major salivary glands include parotid, submandibular and sublingual while minor salivary glands distribute through submucosa of palate, lip and buccal mucosa. The present study was done to evaluate salivary gland tumors in patients referred to Loghman hospital during 1997-2007. In this retrospective descriptive study, patients with salivary gland tumors were studied by means of existing data technique. Data collection sheet included gender, age, location and size of tumor, clinical and pathologic diagnosis, pathological diagnosis and treatment. The histopathological analysis of all cases was meticulously reviewed and classified by 3 expert pathologists. Descriptive analysis was used for the analysis. Forty four patients were found with salivary gland tumors. 36.4% of them were females and 63.6% were males. Benign tumors calculated about 72.7% and malignant tumors as 27.3%. The most common tumors were pleomorphic adenoma [70.4%], warthin tumors [2.2%], and mucoepidermoid carcinoma [11.3%] was the most common malignancies. Parotid [77.2%] was the most common site following by submandibular gland [11.3%] and palate with 11.3% occurrence. The size range of tumors was 1-9 cm with the average size of 2-4cm. Pleomorphic adenoma was the most common benign tumor and mucoepidermoid carcinoma was the most malignant tumor resembling the other studies done in the field

Carcinoma mucoepidermoide central: reporte de un caso / Central mucoepidermoid carcinoma: a case report

Se presenta el caso clínico de un paciente que acudio a la Unidad de Estomatología y Cirugía Bucomaxilofacial del Hospital de Clínicas de La Paz, por dolor tipo urente y lesión ulcerosa en reborde alveolar mandibular izquierdo de aproximadamente 6 meses de evolución; fue sometido a biopsia excisional bajo anestesia general para su respectivo estudio histopatológico, mismo que reporta CARCINOMA MUCOEPIDERMOIDE CENTRAL. La baja frecuencia de esta entidad tumoral maligna motiva su presentación y revisión bibliográfica.

We present the case of a patient who consulted with the Unit ofStomatology and Bucomaxilofacial Surgery of the Hospital deClínicas in La Paz. The patient referred burning pain and an ulcerouslesion on the left alveolar edge of the mandibula of approximately 6months evolution. The patient was submitted to an excision biopsyunder general anaesthesia for the respective histopathologicalexamination. The result showed CENTRAL MUCOEPIDERMOIDCARCINOMA. Given the low frequency of this malignant tumour, wewere motivated to present this case with a bibliographic review.

Incidence of salivary gland tumors: a morphological study at pathology department of king edward medical university / Mayo hospital, Lahore

This study was conducted to see the incidence of the lesions of Salivary Gland. All the cases of salivary tissues submitted to the Pathology Department of King Edward Medical University were taken at the end of year [Jan 2005-Dec2005] and reanalyzed. There were 42 cases of salivary glands, out of which 19[45%] were males and 23[55%] were females. Age range was 12-72 years. Major number of cases [17] were from parotid, whereas 15 were from submandibular, 04 and 06 were from sublingual and minor salivary glands like palate respectively. There were 25[59.52%] pleomorphic adenoma, 01[2.3%], 01[2.3%], 04[9.5%], 07[16.6%] were monomorphic adenoma, lymphoepithelioma, mucoepidermoid carcinoma, adenoid cystic carcinoma respectively. Only 04[9.5%] cases showed chronic sialadenitis

Carcinoma adenoide quístico de glándula sublingual: combinación de cirugía y radioterapia / Cystic adenoid carcinoma of sublingual gland: surgery and radiotherapy combination

El carcinoma adenoide quístico (CAQ) o cilindroma es una rara entidad clasificada por la OMS dentro de los carcinomas de glándulas salivales. Representa sólo el 1 por ciento de todos los tumores malignos de la región bucal y maxilofacial, aunque al hacer referencia a las glándulas salivales, constituye el 5 por ciento de los carcinomas de parótida, submaxilar y sublingual, y aproximadamente el 50 por ciento de las menores. La ubicación más frecuente es en las glándulas palatinas y sus características principales son: crecimiento lento pero persistente, altas tasas de recidiva local y metástasis a distancia, originando la muerte dentro de los 5 a 10 primeros años en aproximadamente el 50-70 por ciento de los casos. Se presenta un caso de localización en glándula sublingual, el cual fue tratado quirúgicamente con posterior radioterapia, obteniendo buenos resultados

Tumores de glandulas salivares mayores y menores / Salivary glands tumors

Se presentan un total de 138 casos de tumores benignos de glandulas salivares mayores y menores ocurridos en un periodo de 20 anos; entre 1963 y 1982 y diagnosticados en el hospital Universitario de Caldas.Se estudia la frecuencia de cada tumor segun las diferentes glandulas afectadas, edad y sexo, principales caracteristicas clinicas de todos los casos, metodos de laboratorio y diagnostico empleados, respuestas a la terapeutica instaurada y caracteristicas anatomopatologicas. Los tumores benignos ocurrieron en el 79.8 x 100 de los casos, correspondiendo al Adenoma Pleomorfico el 65 X 100 de toda la casuistica. Afecta al 62 X 100 de mujeres, principalmente en parotida, lobulo superficial y sin compromiso del Facial que aparece como complicacion postoperatoria en el 23 X 100. Se presentaron 8 casos con recidivas, cuyo principal motivo de aparicion fue probablemente una reseccion defectuosa, entre 2 meses y 16 anos despues de este. No se establece relacion entre el patron histologico predominante y el comportamiento biologico de la neoplasia. Se recomienda control de por vida a estos pacientes y toma mas frecuente de Biopsia preoperatoria que fue considerada inocua. Se presentan ademas cinco casos de Adenomas Monomorfos de Celulas Basales con todas sus caracteristicas clinicas y patologicas, estableciendose como una entidad distinta y diferenciable de algunas variantes de Carcinoma Adenoide Quistico ..
