摘要:

65岁女性,临床表现为肾脏及血液系统系统为主的多系统损害,肾损害主要表现为中等量蛋白尿,低白蛋白血症。肾外有轻度贫血及血小板减少,血清免疫固定电泳提示κ型IgG单克隆免疫球蛋白条带。肾活检组织学改变为足细胞及肾小管上皮细胞肿胀,胞浆内见结晶样物质,免疫病理示其κ轻链阳性,电镜下见菱形、圆形、梭形等多种形状的结晶,免疫胶体金技术证实κ轻链阳性。该患者最终诊断为轻链足细胞病伴轻链肾小管病,考虑浆细胞异常增生性疾病所致。

Abstract:

ABSTRACT A 65-year-old female, was charcterized with multi-system damage including proteinuria, hypoalbuminemia, anemia, thrombocytopenia and serum κ-IgG monoclonal immunoglobulin. Renal biopsy showed swollen podocytes and tubular epithelial cell which contained crystalline inclusions. They were positive staining for κ light chain. Electron microscopy showed all kinds of osmiophilic intracellular inclusions. The final diagnosis was light chain podocytopathy and tubulopathy caused by plasma cell disorders.

Key words: light chain podocytopathy, light chain tubulopathy, plasma cell disorders, renal biopsy
