Granulomatous mastitis as presenting sign of Wegener's granulomatosis

Abstract

A case where a breast tumor was the initial manifestation of Wegener's granulomatosis is presented. Breast biopsy revealed granulomatous mastitis, and treatment with tuberculostatic drugs was started. Following an initial improvement the patient finally died. Postmortem, the diagnosis of generalised Wegener's granulomatosis was made. Although Wegener's granulomatosis is a very rare cause of granulomatous mastitis, it should be considered in the differential diagnosis. A brief outline of the literature is given.
