A 76-year-old woman with classical rheumatoid arthritis presented with a left groin mass associated with radiologic erosion of the adjacent bony public ramus. The hip joint was not involved. Computerized tomography showed an encapsulated cyst of the pubic ramus that was surgically excised and measured about 6 x 8 cm. Histologic examination of the cystic mass and adjacent bone showed marked avascular necrosis, surrounded by an acute necrotizing vasculitis with fibrinoid necrosis. We postulate that, in this case, rheumatoid vasculitis caused an avascular necrosis of the pubic ramus.
一名患有典型类风湿关节炎的76岁女性出现左腹股沟肿块，伴有邻近耻骨支的放射学侵蚀。髋关节未受累。计算机断层扫描显示耻骨支有一个包膜囊肿，手术切除后囊肿大小约为6×8厘米。对囊肿性肿块和邻近骨骼进行组织学检查发现有明显的无血管坏死，周围是伴有纤维素样坏死的急性坏死性血管炎。我们推测，在这种情况下，类风湿性血管炎导致了耻骨支的无血管坏死。
