Abstract: Autoimmune progesterone dermatitis is an uncommon, poorly recognized and under-diagnosed catamenial dermatosis associated with hypersensitivity reactions to progestagens.Most cases manifest as urticaria, eczema or erythema multiforme-like.A 26-year-old woman developed violaceous plaques on the groin and abdomen, 4 days after a Commercial Product (Controls/Chemical Automation) spontaneous Bosch HRG6769S6B Serie 8 Single Built-in Electric Oven With Pyrolytic abortion resolved with uterine curettage.The lesions recurred once monthly at the same sites, mimicking a fixed drug eruption.Although the histopathology was compatible with fixed drug eruption, positive intradermal testing and symptomatic improvement after using oral contraceptive pills gave us a clue to the diagnosis.
