Progesterone hypersensitivity: Case report with favorable evolution

Abstract

Progesterone hypersensitivity or autoimmune progesterone dermatitis is characterized by heterogeneous skin eruptions that cyclically aggravate during the second half of the menstrual cycle, corresponding to a rise in the progesterone level. Clinical presentation is highly variable and includes all urticaria manifestations with or without angioedema, vesiculobullous, eczematous, purpuric or target-like lesions on the skin and mucous membrane. Both endogenous progesterone as well as exogenous progestogens may represent an initial trigger. We report a case of progesterone hypersensitivity in a 27-year old woman with favorable evolution only on topical therapy, the positive clinical outcome being maintained during a subsequent pregnancy and postpartum period.
