Tumour lysis syndrome (TLS) is a serious life-threatening complication of cancer chemotherapy which is a constellation of metabolic disturbances that typically occurs during therapy of bulky, rapidly proliferative tumours. TLS is an oncological emergency that causes a significant release of phosphate, potassium, uric acid, and nucleic acids into the blood stream. Incidence of TLS in multiple myeloma is rare. Here we present a case of multiple myeloma who later developed tumour lysis syndrome in its due course which was rare. A 67-year-old male was diagnosed with Multiple myeloma on the basis of M spike, osteolytic lesions and bone marrow analysis. First cycle of chemotherapy with lenalidomide, bortezomib and denosumab was initiated. During the course of follow up he presented to our casualty with complaints of chills and rigor. Based on the biochemical abnormalities a diagnosis of tumour lysis syndrome was made. He received I.V fluids, anti-hyperkalemic measures, allopurinol. He had neutropenic sepsis and went into septic shock and died after multiple resuscitative efforts.

Multiple myeloma is a neoplastic plasma cell dyscrasia. Anaemia in multiple myeloma is usually related to many factors, of which the commonest cause being anaemia of chronic disease. We reported a 67 years old hypertensive male presented with low back pain and loss of appetite. Investigations revealed severe anaemia and elevated total serum protein with albumin/globulin (A/G) reversal (1:4). Bone marrow aspiration revealed plasma cell dyscrasia. Skeletal survey evaluation showed multiple osteolytic lesions. Serum protein electrophoresis revealed M spike in gamma globulin region with immunofixation suggestive of IgG and kappa monoclonal gammopathy. He was diagnosed as a case of multiple myeloma.. On evaluating the cause of severe anaemia, interestingly various findings suggestive of Autoimmune hemolytic anaemia (AIHA) were found. Packed red blood cell transfusion along with steroids was done for correction of severe anaemia. Review of literature showed that only about 4% of AIHA patients had multiple myeloma. We reported a rare case of multiple myeloma who presented with AIHA.
