A solitary crateriform ulcer of the lower lip: A case report with review of literature

Abstract

Keratoacanthoma (KA) is a relatively common skin lesion. We report a case of KA-mimicking squamous cell carcinoma in a 40-year old smoker, who was also having speckeled leukoplakia on the buccal mucosa. The present case highlights the importance of histopathological diagnosis, as the treatment in latter case is aggressive, which is unnecessary if attempted with KA. Moreover, the present report provides an overview of such lesions, which could be encountered in clinical situations for which definitive diagnosis is of paramount importance before the starting of treatment plan.
