Abstract
- Small cell carcinoma of the colon and rectum is a rare primary epithelial malignancy at this location. Histologically, this tumor represents a spectrum of neuroendocrine differentiation. The neuroendocrine cancers of the colon manifest a highly aggressive behavior, even more than their adenocarcinoma counterpart of the same stage. Small cell carcinoma in the colon has early metastasis and the prognosis is extremely poor. We report a case of small cell carcinoma of the rectum manifesting as femur neck fracture during sleep.
