Presentation

A 27-year-old woman presents with an 18-month history of vulvar irritation. She is otherwise healthy except for episodes of depression. She has tried multiple agents for her condition including topical steroids, Vagisil, antibiotics, and fluconazole. She used oral steroids but developed knee pain. Tacrolimus has not helped. A biopsy revealed lichen simplex chronicus. Immunofluorescent studies were negative.

Correct diagnosis: A. Contact dermatitis

Treatment: Oral agents for symptom control (tricyclic antidepressants or anticonvulsants) may be needed to help avoid overuse of topical agents.
