We describe a patient with rheumatoid arthritis who presented a large femoral-inguinal mass. The mass proved to be a synovial cyst-like structure communicating with rigid cystic lesions at the pubic bone. No obvious communication between the cystic lesions and the hip joint or bursae was seen by hip arthrogram or in surgery. Pathological examination of the cystic lesion at the pubic bone revealed infiltration of multiple rheumatoid nodules with marked fibrinoid necrosis into the bone, with synovium-like tissue on it. However, no synovial tissue was observed in the femoral-inguinal mass. These findings suggest that the femoral-inguinal mass was not a true synovial cyst but can be called a pseudo-synovial cyst arising at the pubic bone region.
我们描述了一名患有类风湿性关节炎的患者，其出现了一个较大的股-腹股沟肿块。该肿块被证明是一个滑膜囊肿样结构，与耻骨处的硬性囊性病变相通。通过髋关节造影或手术未发现囊性病变与髋关节或滑囊之间有明显的连通。耻骨处囊性病变的病理检查显示多个类风湿结节浸润入骨，伴有明显的纤维素样坏死，表面有滑膜样组织。然而，在股-腹股沟肿块中未观察到滑膜组织。这些发现表明，股-腹股沟肿块并非真正的滑膜囊肿，而是可称为起源于耻骨区域的假性滑膜囊肿。
