A case of menstrual dermatitis is reported. A 31-year-old woman presented in September of 2000 with a three-year history of a papular eruption on her trunk. The eruption occurred cyclically, appeared approximately five days prior to the menses, and resolved following the memses. She was treated on several occasions with corticosteroids, antibiotics, antihistamines, or androgen-progesterone complex hormone without much improvement. Physical examination revealed slightly itchy, indurated papules on her frontal trunk. Laboratory tests results including antinuclear antibodies and various hormones were mostly within the normal range. Histopathological examination showed an inflammatory infiltrate around dermal vessels and exocytosis. The cells were mostly lymphocytes. An intradermal skin test for progesterone was administered ; the result was negative. We diagnosed the cases menstrual dermatitis. However, no intradermal skin test for estrogen has been administered ; this test has produced positive results in cases of estrogen dermatitis. Further tests are required to determine the diagnose and therapy in this case.
