Multiple Myeloma in a 27-Year-Old Female Presenting with Recurrent Low Back Pain

Multiple Myeloma or Kahler's disease is a neoplasm characterized by proliferation of plasma cells in bone marrow where the most common clinical manifestations include bone pain secondary to osteolysis, kidney damage and hypercalcemia. The most common risk factors associated with this pathology are advanced age, family history of multiple myeloma, alcoholism, smoking, among others. Diagnosis includes the presence of monoclonal protein or paraprotein in serum and urine by electrophoresis, presence of free chain protein in 24-hour urine and immunofixation in serum. We present a clinical case of a 27-year-old female patient who presented lumbar pain as the initial manifestation and on requesting laboratory tests showed alterations compatible with myeloma. Laboratory studies were requested confirming the diagnosis of Multiple Myeloma kappa stage ISS-III in current treatment with cyclophosphamide, dexamethasone and thalidomide.
