Introducción: el linfoma con células en anillo de sello es una entidad poco frecuente y simuladora de neoplasias epiteliales, sarcomas y condiciones reactivas de histiocitos. Representa una variante morfológica de distintos linfomas no Hodgkin, por lo que su diagnóstico puede representar un desafío ...
SUMMARY: The group of primary renal tumours with granular-oncocytic cytoplasm is a very heterogeneous group, in its histological origin and biological behavior resulting in many diagnostic problems. In this study 57 renal epithelial tumours with granular oncocytic cells were analyzed using fluorescence i...
Introduction The pineal gland is a common location for intracranial germ cells, but
dermoids are not commonly observed in this area. In the present paper, we discuss the
clinical and radiological features as well as the treatment and outcome of this cyst in a
6-year- old child with a pineal dermoid cyst....
Abstract Objective To estimate the cytological and colposcopic performances for the diagnosis of cervical neoplasias. Methods Cross-sectional retrospective study with data from patients' charts. The participants underwent colposcopy, guided biopsies, and excision when needed. The cytological and colp...
