Autoimmune progesterone dermatitis.

Autoimmune progesterone dermatitis is a rare cutaneous disorder characterized by recurrent cyclic eruptions during the luteal phase of the menstrual cycle. We describe a woman with postpartum onset of a papulovesicular eruption. The possibility of autoimmune progesterone dermatitis was raised because of the cyclic nature of the outbreak. A reactive intradermal progesterone test confirmed the diagnosis. A review of individual case reports is also presented.
