Systemic polyarteritis nodosa diagnosed at hysterectomy.

A 61-year-woman was referred because of declining general health. A diagnosis of uterine malignancy was suspected on the basis of uterine enlargement and an elevated erythrocyte sedimentation rate. Hysterectomy was performed, and histologic examination revealed necrotizing vasculitis affecting the ovaries, fallopian tube, and uterus. Muscle biopsy showed typical periarteritis nodosa lesions. Despite the scarcity of such cases, the incidental finding of necrotizing arteritis in a surgical uterine specimen warrants further investigation to determine if the vasculitic process is localized.
