Diaper dermatitis candidiasis - Anogenital in
An alkaline pH in the diaper area predisposes a patient to candidal diaper dermatitis. In both children and adults, fecal bacteria further alkalize urinary pH, which increases the risk of candidal infections. Breast-fed infants have a lower incidence of diaper dermatitis than formula-fed infants, which is theorized to be secondary to a lower stool pH in the breast-fed infants. Furthermore, patients with a defective Th17 response are predisposed to recurrent cutaneous candidal infections.
In adults, risk factors for candidal diaper dermatitis include urinary and fecal incontinence, diabetes mellitus, obesity, human immunodeficiency virus (HIV) infection, antibiotic use, systemic immunosuppressive medications including corticosteroids, prolonged hospitalizations, nursing home stays, and bedbound patients.

- In psoriasis, no satellite lesions are usually seen. Psoriatic lesions are also erythematous and well demarcated but are usually covered in silvery scale outside of moist skin areas such as intertriginous zones. Psoriatic plaques can also be found outside of the diaper. See also flexural psoriasis.
- Irritant diaper dermatitis
- Allergic contact dermatitis
