A case of catamenial erythema multiforme major successfully treated with goserelin.

A group of menstrual cycle-related dermatoses and hypersensitivity syndromes exist but are rarely reported in the literature. A history of recurrent cutaneous eruptions in premenopausal females should be considered in the context of the menstrual cycle. The diagnosis of menstrual cycle-related dermatoses is largely clinical, although provocation testing can assist. Treatment options are broad and are aimed at reducing the immune response and/or suppressing ovulation. Goserelin may accumulate and have a gonadotrophin-suppressing effect for longer than expected.
