Summary

Keratoacanthoma is a lesion typical crater, symmetrical, rounded, rapid growth with high potential for self-involution. The lesions may be multiple, disseminated and associated with some syndromes. The etiology of keratoacanthoma is not known, but it is often observed in patients chronically exposed to sun. Histopathological features of keratoacanthoma may resemble those of a well differentiated squamous cell carcinoma. The hallmark of the disease is spontaneous resolution after an intermediary stationary stage. The majority of the cases is treated by surgical excision. For this reason, very few cases have been documented until resolution, which constitutes the gold standard for this clinic diagnosis. The aim of this article is to report a case of keratoacanthoma in the inferior lip of an immunosuppressed patient.
