Autoimmune progesterone dermatitis

Abstract

Autoimmune progesterone dermatitis is a rare cutaneous disorder characterized by recurrent cyclic eruptions with variable morphology occurring during the luteal phase of the menstrual cycle. We report a case of a 40-year-old woman with recurrent pruritic eruptions of 8 years' duration. The possibility of autoimmune progresterone dermatitis was raised because of the cyclic nature of the exacerbations. We used oral estrogen both to confirm the diagnosis and to treat the patient. A brief review of the clinical features of the disease is also presented.
