An 8-year-old boy developed a rapidly growing tumor of the leg. The lesion was characterized by a central keratinous plug and suggested neoplasia. Biopsy revealed keratoacanthoma. There is a problem of differentiation of keratoacanthoma from squamous cell carcinoma; conservative management of this benign tumor in children is indicated.
