title: Association of adenocarcinoma and leiomyosarcoma of the sigmoid colon. A case report.
abstract: Malignant tumors of the gastro-intestinal tract showing both carcinomatous and sarcomatous components are rare. Very few cases were described in the stomach and only one case in the colon. We describe a second case of a tumor of the sigmoid colon showing adenocarcinoma intermingled with leiomyosarcoma elements.
