Acanthoma fissuratum cutis. Report of a case and a review of previous cases.

Acanthoma fissuratum cutis is a benign cutaneous lesion apparently caused by constant minor trauma. In the case here reported it seemed to have been caused by poorly fitting spectacles. Since a lesion of this type may be mistaken for a basal-cell epithelioma, its accurate diagnosis will spare the patient needless surgery and expense.
