Multiple myeloma developed in a woman with a 7-year history of seropositive rheumatoid arthritis (RA). An unexpected finding was the presence of massive amyloid deposits in the left femur and traces of amyloid in the synovium. Detailed histopathologic studies, however, conclusively excluded amyloid arthropathy. Although definitive tissue classification was not possible, this patient in all likelihood had 2 types of amyloid: massive bone lesions of myeloma-associated (AL) amyloid, and focal subsynovial deposits of RA-associated secondary (AA) amyloid.
一名患有血清阳性类风湿性关节炎（RA）7年的女性发生了多发性骨髓瘤。一个意外发现是左股骨中有大量淀粉样沉积物，滑膜中有淀粉样物质痕迹。然而，详细的组织病理学研究最终排除了淀粉样关节病。尽管无法进行明确的组织分类，但该患者很可能有两种类型的淀粉样物质：骨髓瘤相关（AL）淀粉样物质的大量骨病变，以及类风湿性关节炎相关继发性（AA）淀粉样物质的局灶性滑膜下沉积物。
