Primary squamous cell carcinoma of the cecum.

Primary squamous cell carcinoma (SSC) of cecum is a very rare malignant neoplasm. The first case was reported by Schmidtman in 1919. Here, a well-differentiated, keratinizing SSC of cecum in a 34-year-old male patient is being reported. The neoplasm originated from surface epithelium, and invaded the bowel wall up to subserosal fat space. No predisposing factor was detected. Clinical features were that of an adenocarcinoma of the colon. Postoperative chemotherapy was given for 6 months to eradicate any micrometastasis. The patient is free of disease 2 years after having had the tumor removed. The case is being presented because of its rare occurrence.
