Carcinosarcoma of ileum in regional enteritis.
A biphasic malignant neoplasm, carcinosarcoma, arose in a segment of ileum involved with regional enteritis. The tumor spread throughout the abdomen, and the patient died nine months after diagnosis. The spectrum of intraepithelial dysplasia, carcinoma with varying degrees of differentiation, and sarcomatous-appearing elements suggests that the histogenesis of this tumor is epithelial. This report provides further documentation of the relationship between regional enteritis and unusual neoplasms of the intestine.
