Abstract
BACKGROUND: Autoimmune progesterone dermatitis is a rare eruption that recurs monthly as progesterone levels peak during the menstrual cycle. Clinical and histologic features are variable, and the eruption is thought to represent a hypersensitivity response to endogenous progesterone. METHODS: We present the case of a 38-year-old woman with a pruritic intermittent facial eruption of 18 months' duration that recurred predictably in the days surrounding menses. RESULTS: The histology showed interface dermatitis with features of both erythema multiforme and urticaria. Intradermal injection of medroxyprogesterone acetate was positive. Her symptoms responded to antihistamine therapy. CONCLUSION: This unusual case is particularly distinctive both in terms of the histologic findings and the response to therapy.
