Multiple unusual manifestations of Wegener's granulomatosis: breast mass, microangiopathic hemolytic anemia, consumptive coagulopathy, and low erythrocyte sedimentation rate.

We describe a patient who presented with multiple unusual manifestations of Wegener's granulomatosis, including a breast mass, microangiopathic hemolytic anemia, and consumptive coagulopathy. Erythrocyte sedimentation rate (Westergren), usually elevated in the course of this disease, persistently remained low in this patient. We found that C-reactive protein levels were, in this case, a more sensitive gauge of disease activity.
