Urothelial carcinomas have an established propensity for divergent differentiation. Most of these variant tumors are muscle invasive but not all. The response of non muscle invasive variant tumors to intravesical immunotherapy with BCG is not established in the literature, and is reported here. Between June 1995 and December 2007, 760 patients (mean age of 67.5 years) underwent transurethral re...

OBJECTIVE To analyze the magnetic resonance (MR) imaging findings of invasive micropapillary carcinoma of the breast. MATERIALS AND METHODS MR images were retrospectively evaluated in 14 patients (age range: 37-67, mean age: 49 years) with pathologically confirmed invasive micropapillary carcinoma of the breast. The enhancement type (mass/non-mass), shape, margin, contrast enhancement, and ti...

The computational model presented in this paper focuses on modeling ductal carcinoma in situ (DCIS), which is the most commonly detected preinvasive form of breast cancer. The model aims to understand the biological mechanisms and resultant growth dynamics of DCIS. The cellular automaton model based on observed phenotypic characteristics of DCIS emphasize the important role of contact inhibitio...

Objective: To analyze the clinicopathological spectrum of urothelial carcinoma of urinary bladder. Study Design: Descriptive case series. Place and Duration of Study: Armed Forces Institute of Pathology (AFIP), from 1st January 2012 to 31st October 2013. Patients and methods: All cases of urothelial carcinoma were retrieved from AFIP tumour registry. Age, gender, histological type, grade and va...

BACKGROUND Pulmonary adenocarcinoma (PA) is the most common histologic type of primary lung cancer. Generally, adenocarcinoma was composed by five major components. The present study aimed to evaluate changes in the composition of adenocarcinoma components as the tumor grows; in addition, to analyze the correlation between the occupancy rates of histologic components of the tumor in regard to p...
