Diffuse Large B Cell Lymphoma is the commonest subtype of Non-Hodgkin’s Lymphoma. It may present with primary nodal or extranodal involvement. Up to 40% of patients present with primary extranodal involvement, the commonest involved sites being gastrointestinal tract, testes, central nervous system, thyroid, nose, sinuses, skin, breast, bone and respiratory tract. Skeletal Muscle is a rare site of primary lymphomatous involvement. We present a case of Diffuse Large B Cell lymphoma primarily involving the skeletal muscles and breast, initially managed as a case of acute pyogenic myositis with sepsis with Multiple Organ Dysfunction Syndrome. In addition, the patient had hypercalcemia, cortical vein thrombosis, proteinuria and renal dysfunction, which were all speculated to be paraneoplastic in etiology.
