Primary linitis plastica of the colon.Report of two cases and review of the literature

Abstract

Two cases of primary linitis plastica of the large intestine will be presented and discussed. Characteristic clinical features of this type of adenocarcinoma of the large intestine include younger age of presentation, low incidence of hepatic metastasis and a high incidence of ovarian, lymph node and peritoneal metastasis. Pathological features reveal thickening of the intestinal wall by diffuse infiltrating tumor cells of the characteristic signet ring cells, abortive glands and undifferentiated or anaplastic cells. The prognosis is poor.
