Composite carcinoma of the colon: A case report with literature review

Abstract

Mixed composition carcinomas of the large intestine are rare. The aggressiveness of these malignant tumors depends on the components of the tumor. We present the case of a middle-aged man who developed an acute surgical abdomen due to perforation of a mixed composition carcinoma with a dominant small cell component. To the best of our knowledge this is the first case report of a composite cecal carcinoma with lymph node metastases from both the small cell and adenocarcinoma components.
