[Geometric phagedenism. Clinico-therapeutic experience]

A woman of 35 years old, in good physical condition, developed multiple lesions of Phagedenisme Geometrique (Pyoderma Gangrenosum) in the gluteal region and the thigh. Corticoids and antibiotics were used at high dosages resulting in healing of the center of the lesions but without any effect on the periphery. Plasma transfusions were then given, resulting in apparent amelioration of the peripheral abcesses. Her general condition was not altered during the entire course of the disease. Septic foci were not demonstrated and a minimal dysproteinemia was neither significant nor persistent.
