Primary Linitis Plastica of the Colon with Mucinous Adenocarcinoma in Young Woman

ABSTRACT

Adenocarcinoma is the most common pathologic diagnosis, representing >95% of colorectal cancers; mucinous adenocarcinoma (MA) accounts for 10-15% and SRC accounts for 0.1-2.4% of colorectal cancers. MA is defined as a tumor with > or =50% mucin. Patients with MAs have a poor prognosis, a higher proportion of peritoneal metastases, and present at a more advanced stage of disease. Linitis plastica involving the colon and rectum is usually a metastatic lesion from gastric cancer and other organs, such as the prostate, gallbladder, and breast. Primary linitis plastica of the colon is very rare. We managed a case of colon cancer occurring in a 19-year-old female with a histologic diagnosis of mucinous adenocarcinoma and morphologic features of linitis plastica. Herein we report a rare case of primary linitis plastica of the colon with a review of the literature.
