[A case report of IgD myeloma with acute renal failure and deposition of lambda light chain along the tubular basement membrane].
A case of IgD lambda type multiple myeloma that developed acute renal failure was presented. Histopathologic studies revealed apparent myeloma cast nephropathy with typical giant cells and light chain deposition along tubular basement membrane and inter-peritubular interstitium. Glomerular deposits of light chain were absent by electron and immunofluorescent microgram. The presented case showed a very uncommon histopathologic findings of unusual deposits of light chain, to tubulo-interstitium except for glomeruli, in addition to vertically rare IgD myeloma. A sixty-year old female who was suffered from acute renal failure and treated by hemodialysis for one month was admitted to our institute. Physical examinations revealed ill-apparent and emaciated uremic patient on admission. Laboratory and radiological studies demonstrated IgD lambda type monoclonal protein and numerous punched out appearance of skull bone. The diagnosis of IgD lambda myeloma was confirmed with aspiration bone marrow test. Anti-myeloma therapy of melphalan and prednisolone have started, however, fatal arrhythmia suddenly suffered the patient and resuscitation attempts failed to get any success one week after admission. Renal necropsy was performed and specimens were studied by light, immunofluorescent and electron microscope.(ABSTRACT TRUNCATED AT 250 WORDS)
