To the Editor:—
The granuloma fissuratum is often seen by dentists and others with a penchant for contemplating oral cavities. Sutton1 first described it 35 years ago as a circumscribed, firm, fissured, fibrotic tumor of the labioalveolar fold. It remained for Epstein,2 and then Fretzin,3 to point out that a mate lesion occurs in the retroauricular fold. In either location it is easily recognized.
Report of a Case:—
A 55-year-old white physician was observed for a 1 1/2 × 1 1/2 -cm, lilac-colored, firm nodule which had been present for several months in the left retroauricular fold. Its arresting feature was an extremely neat crease coursing the entire tumor vertically. The etiologic challenge was satisfied when the gentleman replaced his eyeglasses and it became evident that the plastic earpiece fit snugly into the accomodating furrow in the tumor.The earpiece was realigned, thus removing the constant trauma
