Multiple scrotal epidermolytic acanthomas; secondary to trauma?Clin Exp Dermatol. 2004 Sep; 29(5):489-91.CE
Epidermolytic hyperkeratosis (EH) is an abnormality of epidermal maturation, most commonly due to mutations in keratins 1 and 10, which may be a congenital or an acquired defect. The term epidermolytic acanthoma was applied to a solitary discrete epidermal proliferation characterized by EH. Subsequently there have been several reports of disseminated epidermolytic acanthomas. We report a rare case of multiple epidermolytic acanthomas localized to the scrotum. With the aetiology of epidermolytic acanthoma unknown, trauma has been postulated as a possible cause. Our patient repetitively scratched his scrotum for 5 years and we believe that this action triggered his multiple scrotal epidermolytic acanthomas.
