ABSTRACT Solitary fibrous tumor (SFT) is a rare mesenchymal spindle-cell neoplasm commonly found in the pleura; it is rare in the orbit and extremely rare in the lacrimal gland. We herein report a case of SFT of the lacrimal gland that mimicked a pleo morphic adenoma. We discuss the clinical, radiologica...

ABSTRACT Objective Fine-needle aspiration cytology is a valuable method for preoperative assessment of head and neck tumors. However, its accuracy in detection of salivary gland masses is controversial compared with other methods. The aim of this work was to evaluate the effectiveness and accuracy of f...
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 patien...

Abstract Introduction: A key step of cancer development is the progressive accumulation of genomic changes resulting in disruption of several biological mechanisms. Carcinoma ex-pleomorphic adenoma (CXPA) is an aggressive neoplasm that arises from a pleomorphic adenoma. CXPA derived from a recurrent PA ...
Introducción: El Siringoma Condroide o tumor mixto es una neoplasia habitualmente benigna que constituye 0,01 por ciento de los tumores primarios de la piel. Es una entidad análoga al tumor mixto (Adenoma Pleomorfo) de glándulas salivales. El diagnóstico es exclusivamente histopatológico.
Objetivo: ...
Introdução: As neoplasias das glândulas salivares têm amplo espectro histológico resultante da múltipla diferenciação celular tumoral. O adenoma pleomórfico (AP) e o carcinoma adenoide cístico (CAC) são as mais comuns neoplasias benignas e malignas provenientes do ducto intercalado, respectiva...

INTRODUCTION: Benign tumors of the parotid gland comprise the majority of salivary gland tumors. OBJECTIVE: To review the clinical characteristics of parotid gland tumors submitted to surgical treatment by the same surgeon. METHODS: Retrospective study with 154 patients who had parotid gland tumors. Clin...
Pleomorphic adenoma, the most common salivary gland tumor, consists of epithelial and mesenchymal components. Its morphologic complexity results from differentiation of tumor cells into fibrous, hyalinized, myxoid, chondroid and osseous areas. The diagnosis is made by the clinical and histo pathological ...
No presente trabalho foram estudados 35 adenomas pleomórficos, provenientes de biópsias do Serviço de Anatomia Patológica dos Hospitais Universitários Pedro Ernestro e Antonio Pedro. Do total, foram selecionados sete, que apresentavam, em seus parênquimas, sólidas massas de epitélio glandular, co...
