Paciente HIV-positivo com aumento de volume bilateral da glândula parótida: Relato de caso. / HIV-positive patient with bilateral swelling of parotid gland: Case Report

Introdução: Pacientes HIV-positivo são acometidos por váriossinais e sintomas na região de cabeça e pescoço, sendo o aumentode volume de uma glândula salivar um achado comum. A glândulaparótida é a mais afetada, com frequente comprometimentobilateral. Objetivo: Chamar a atenção para a pesquisa de HIVem pacientes adultos com aumento de volume das glândulassalivares, principalmente a parótida, uma vez que pode ser aprimeira manifestação da infecção viral. Relato de caso: Opresente artigo relata um caso de um paciente masculino, adulto,com aumento de volume bilateral de glândula parótida, associadoà linfadenomegalia cervical generalizada. Após avaliaçãoclínica e tomográfica, solicitou-se exame sorológico para HIV, oqual confirmou positividade. O paciente foi encaminhado paratratamento. Comentários finais: O presente caso ressalta aimportância do exame minucioso da região de cabeça e pescoço,e a correlação do aumento de volume da glândula parótida empacientes infectados pelo HIV.

[Minor salivary gland tumours: a 10-year study]. / Neoplasias de glándulas salivales menores: estudio de 10 años.

Salivary gland tumours represent between 2 % and 6.5 %, approximately, of all head and neck tumours. The aim of this paper was to identify the frequency of minor salivary gland tumours among patients in the Oral Medicine Clinic of the Federal University of Paraná during the period from 1997 to 2007. A retrospective study was conducted on 1,923 histopathological analyses of oral lesions. Fourteen cases of salivary gland tumours were found, of which 7 were benign and 7 malignant. The lesions were localized mainly in the palate (71.5 %). By histological type, 50 % of the lesions were characterized as pleomorphic adenoma, 28.6 % mucoepidermoid carcinoma, 14.3 % cystic adenoid carcinoma and 7.1 % as polymorphous adenocarcinoma. These findings suggest that salivary gland tumours have a low incidence in the population and that the pleomorphic adenoma is the most common type of tumour, followed by mucoepidermoid carcinoma.

Neoplasias de glándulas salivales menores: estudio de 10 años / Minor salivary gland tumours: a 10-year study

Las neoplasias de las glándulas salivales representan aproximadamente un 2-6,5 % de todos los tumores de la cabeza y cuello. El objetivo de este trabajo es identificar la frecuencia de neoplasias de glándulas salivales menores en pacientes de Medicina Oral de la Universidad Federal de Paraná atendidos de 1997 a 2007. Se realizó un estudio retrospectivo mediante el análisis de 1.923 laudos histopatológicos, y se halló 14 casos de neoplasias de glándulas salivales. Las lesiones encontradas fueron 7 tumores benignos y 7 malignos. Las alteraciones, en su mayoría, se encontraban en la mucosa palatina (71,5 %). En cuanto al tipo histológico, el 50 % se caracterizó como adenoma pleomorfo; el 28,6 %, como carcinoma mucoepidermoide; el 14,3 %, como carcinoma adenoide quístico, y el 7,1 %, como adenocarcinoma polimorfo. Estos resultados permiten concluir que las neoplasias de glándulas salivales tienen una baja incidencia en la población y que el adenomapleomorfo es el tipo de neoplasia más común, seguido del carcinoma mucoepidermoide (AU)
