A nodule with a groove overlying the ear.

Acanthoma fissuratum is a thickening of the skin where the glasses sit.


A papule, nodule or thickening of the skin overlying the ear where the glasses sit is characteristic. A groove exists along the contact point between the glasses and skin.


The lesion may resemble a basal cell carcinoma and any suspicious lesion should be biopsied. Otherwise, no treatment is needed.
