Jacquet erosive diaper dermatitis is a rare condition involving the genital region. It is thought to be a manifestation of a severe 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 postgastrointestinal or postgenitourinary surgery where incontinence has developed.

 Jacquet erosive diaper dermatitis may also be a sign of physical neglect.
