Abstract
Communication about two patients with Wegener's granulomatosis of the mamma. In both cases the rare disease was detected on the occasion of a mammographic examination. The results of the mammography could cause misinterpretations, e.g. it might be mistaken for an advanced mamma carcinoma. Up to now, the manifestation of a Wegener's disease of the female breast was neither mentioned in collective statistics of more than 324 cases nor it could be found in examining the publications of additional 231 cases. Both patients showed an unusual course of the disease with a slow progression as well as an unimportant affection of the respiratory tract. The regression of the tumor like lesions in the breast was remarkable.
