Study regarding the microscopic aspects of pilo-sebaceous units after antiandrogen treatment in hirsute women.

Aim: To analyze the morphological data of pilo-sebaceous units in hirsute women before and 12 months after the antiandrogen treatment with Cyproterone acetate (CPA) 100 mg÷day.

Materials And Methods: Fourteen female patients with idiopathic hirsutism that followed an antiandrogen treatment with CPA were biopsied from the androgen-dependent area of the chin before and 12 months after the treatment. Routine sections were stained with Hematoxylin-Eosin, Masson, Van Gieson, Sirius red and picric-indigocarmine, while additional sections were immunostained for S100 protein and vimentin.
