A neoplastic proliferation characterized by plasma cell accumulation in the bone marrow with presence of monoclonal protein in the serum and/or urine.
Signs & Symptoms
Bone pain and pathological fractures, lethargy, weakness, dyspnea, pallor, tachycardia, recurrent infections, related organ or tissue impairment such as bone disease, renal impairment, hypercalemia, hyperviscosity, amyloidosis.

Peripheral blood characteristics
Normochromic, normocytic anemia or macrocytic anemia. Rouleaux formation. Neutropenia and thrombocytopenia.
Bone marrow characteristics
Increased plasma cells.
Important investigations & related results
Monoclonal protein in serum and/or urine. Immunophenotype of malignant plasma cells: CD38high, CD138high and CD45low. Increased serum calcium and normal serum alkaline phosphatase. Increased serum creatinine in certain cases. Low serum albumin in advanced disease. Raised serum β2-microglobulin.
Treatment & management
Allogeneic stem cell transplantation. Intensive therapy for patients aged less than 65 – 70 years old. It is a combination of several courses of chemotherapy. Non-intensive therapy for older patients involves oral alkylating agent melphalan, sometimes in combination with prednisolone. Other treatments are thalidomide, bortezomib, α-interferon and radiotherapy with other supportive care.
