Abstract Diaper area granuloma of the aged is a skin problem in the diaper contact area among elderly people. We report a case of an 84-year-old man with urinary catheter, presenting with cerebral infarction and a 2-month history of clusters of reddish and flat topped nodules on his genitocrural area. His histological examination of the nodules revealed parakeratosis, acanthosis, and perivascular inflammatory cell infiltration, and vascular dilation in dermis. These conditions were caused directly by constant contacts to diapers with feces. The primary treatment and prevention would be to avoid any irritants and to keep the lesion clean.
