Primary linitis plastica carcinoma of the colon: a case report.

Primary linitis plastica carcinoma of the colon is rare. Most lesions are located on the left side of the colon and these tumors often involve the lymph nodes, peritoneum, and ovaries. We report a case of primary linitis plastica of the sigmoid colon in a 32-year-old Chinese woman who presented with a 7-month history of constipation and associated abdominal pain and tenesmus. Colonoscopy and barium-enema studies showed a stricture at the sigmoid colon. The patient underwent radical surgical resection and received adjuvant radiation therapy and chemotherapy. She died 12 months after the initial diagnosis. The poor prognosis seen with this tumor is due largely to a delay in diagnosis. With increasing familiarity with this tumor, it is hoped that earlier diagnosis and curative surgery will be possible, leading to improvement in survival.
