We report a case of perianal pseudoverrucous papules and nodules in an elderly patient who developed a characteristic diaper dermatitis after infrequent diaper change. The perianal papulonodular lesions improved after saline wet dressing and topical steroid application. These perianal pseudoverrucous papules and nodules indicate a unique type of irritant diaper dermatitis, which can be distinguished from Jacquet erosive diaper dermatitis and granuloma gluteale adultorum. Identifying this condition is important because pseudoverrucous papules and nodules can resemble more serious dermatoses, leading to unnecessary investigations being carried out.Keywords: diaper dermatitis, irritant dermatitis, Jacquet erosive diaper dermatitis, granuloma gluteale adultorum
