Giant clear-cell acanthoma with keratoacanthoma-like changes: a case report.Dermatol Online J. 2006 May 30; 12(4):11.DO
Clear cell acanthoma is a benign epidermal lesion with a variable clinical appearance and distinct histopathology features. Although, it is considered an entirely benign entity, few case reports describe unusual or atypical variants of clear cell acanthoma. We observed a case of a large clear cell acanthoma that also has features of a keratoacanthoma.
