Squamous cell carcinoma of the rectum, primary or metastatic?

Abstract

Primary squamous cell carcinoma of the rectum is very rare. In this article we report a case of squamous cell carcinoma arising from an ovarian dermoid cyst presenting as a rectal mass with gastrointestinal symptoms. To the best of our knowledge, this clinical presentation has not been reported before. This article emphasizes the importance of applying the appropriate guidelines before assigning the diagnosis of primary colorectal squamous cell carcinoma , since the treatment and the management are different.
