Jacquet erosive diaper dermatitis is a rare condition involving the genital region. It is thought to be an irritant dermatitis. Patients often have bowel or bladder incontinence in conjunction with an occlusive environment, often found with diapers. Patients typically present with pruritic papules / nodules and erosions. The condition has been described in children older than 6 months into adulthood, all with common environmental exposure to absorbent garments and a history of incontinence. This condition has also been reported in post-gastrointestinal or post-genitourinary surgery where incontinence has developed.

The clinical presentation includes papules or nodules with overlying superficial erosions as well as erosions or ulcers with elevated borders in the genital or perirectal region. Some reports of pseudoverrucous lesions can be found. Patients often experience pruritus and burning.

Treatment can be difficult; the most effective treatment reported is normalization of the local integumental environment and of bowel / bladder habits.
