Disseminated epidermolytic acanthoma probably related to trauma

Epidermolytic acanthoma is a rare benign tumour, which may occur in both is olated and disseminated forms. Only seven cases of disseminated epidermolyt ic acanthoma (DEA) have been described. This entity should be distinguished from other hereditary or acquired conditions which involve epidermolytic h yperkeratosis and other benign acanthomas. On the basis of the clinical his tory and the histological findings, we diagnosed a case of DEA which was pr obably secondary to repeated trauma.
