[Postovulation dermatitis (dermatitis caused by progesterone)].

Postovulation Dermatitis is a frequent clinical picture although it is not well known. Clinically a polymorphous eruption appears between than 8 or 10 day before menses. The Authors report three cases in which an complete immunological investigation was performed. They conclude that there is no objective evidence of the autoimmune pathogeny of this picture in spite of the clinical relationship between the dermatitis and the ovulation. Therefore they suggest that diseases should be described as "Postovulation Dermatitis" instead "Autoimmune Progesterone Dermatitis".
