Two cases of diaper area granuloma of the adult.

Two cases of diaper area granuloma are reported. Patient 1, a 34-year-old man, had multiple reddish-purple nodules over the diaper area of the right part of the genitocrural region. Candida albicans was not detected from the lesion. Histological examination of the nodule showed acanthosis and dense infiltrates. The granulomas became smaller and flatter after the control of urination. Patient 2, a 28-year-old man, had two large decubitus lesions and multiple nodules over the diaper area of the gluteal region. The decubitus became smaller and the granulomas disappeared after the lesion was kept clean. Because these granulomas resemble granuloma gluteale infantum, but occurred in adults rather than in the aged or infants, we propose to call this condition "granuloma gluteale adultorum." We suggest that these granulomas may represent an inflammatory reaction to the irritation of urine or feces. It is, therefore, of great importance to treat and prevent this condition by controlling the flow of urine and keeping the region clean.
