Keratoacanthoma in the cutaneous area of the upper lip : A case report

Case description: A 53-year-old woman complained of a painless, aesthetically unpleasant brownish, hard lesion in the cutaneous area of the upper lip. The lesion had grown rapidly in the last 30 days (size: ~10×5 mm), and was associated with a hot waxing hair removal. Surgical excision was the treatment chosen in order to differentiate the lesion from squamous cell carcinoma (SCC). An oval-shaped incision was created with an in-depth wedge shape for the removal of the lesion and better approximation of the edges after synthesis. Histopathological analysis confirmed the diagnosis of KA. After 2 years, the patient was completely satisfied with the treatment, and no scar was evident.
