We refer in the present article, the first case found in our laboratory of Monoclonal gammapathy of the IgD type. A 47-year-old man presented at the emergency department with a history of malaise, lethargy, tiredness, thirstiness and obscure depositions. Clinical examination revealed a normocytic anaemia. The plasma urea was 423 mg/dl and the plasma creatinine was 15, 3 mg/dl. He was admitted to hospital with a diagnosis of acute renal failure. The later electrophoresis in serum revealed a little monoclonal band that was identified as IgD-lambda type by immunofixation electrophoresis. In urine electrophoresis was observed a beta-band. Bone marrow biopsy revealed a 20% of plasmocytic cells. Renal biopsy was compatible with myelomatose lesions. Osteolytic lesions were observed.
