Metastasis of carcinoma of buccal mucosa to small intestine causing ileal perforation.

Oral cancers rarely metastasize to the small intestines. In a previously operated case of squamous cell carcinoma of buccal mucosa without any known preoperative distant metastases, we report a case of solitary ileal perforation 3 months after the surgery. The edge of the ileal perforation was positive for squamous cell carcinoma on histopathology. It is important to remember metastases as a cause of acute abdomen in the prior history of oral malignancies.
