Keratoacanthomas (KAs) are a cutaneous condition of skin and mucous membrane neoplasms occurring on sun-exposed areas of light-skinned people. The fact that these tumors can be either benign or malignant fosters controversies about KAs to this day. Histopathology resembles squamous cell carcinoma (SCC) but unlike SCC, KAs will usually self-resolve. Keratoacanthomas can be isolated lesions or multiple-lesion syndromes. Depending upon the patient and the lesion(s), the patient can be treated in a variety of ways to reduce cosmetic and/or physical deformity. This paper presents the pathology of KAs, its clinical forms, and management of these lesions
