Vulvitis circumscripta plasmacellularis mimicking child abuse.

Vulvitis circumscripta plasmacellularis (VCP) is a rare, benign vulvar disorder that is typically described in adult women. Our case occurred in an 8-year-old girl. The primary diagnostic concern was sexual abuse. VCP may also mimic lichen sclerosus, extramammary Paget's disease, pemphigus vulgaris, fixed drug eruption, squamous cell carcinoma, candidiasis, allergic contact dermatitis, and herpes simplex infection. Evaluation should include a biopsy because the histopathologic features of VCP are distinctive.
