Abstract

Epidermoid cysts are very common and therefore relevant to Family Medicine physicians in the primary care setting. Epidermoid cysts can undergo transformation if they become infected or ruptured, resulting in keratin granulomas. Importantly, these may be misdiagnosed or confused with malignancy and should be differentiated histologically after excision if a presumed epidermal cyst has an atypical presentation. In this article we are reporting a case of temporal keratin granuloma as a result of an epidermoid cyst rupture in a middle-aged man.
