Hypercalcemia: Uncovering a rare case of skeletal muscle non-hodgkin's lymphoma

Abstract

We report a case of an 80-year man who presented with a two-week history of confusion and poor oral intake. He was found to be dehydrated with acute kidney injury, hypercalcemia, and pancytopenia. A previously undetected right leg mass was discovered. Radiologic studies of the right knee found a fibula shaft fracture. MRI confirmed this finding and showed the presence of a heterogeneous mass involving most of the calf muscles. Biopsy confirmed the diagnosis of a rare musculoskeletal non-Hodgkin's lymphoma of the right leg. A brief discussion to this type of pathology follows this rare presentation.
