T cell Non-Hodgkins lymphoma as a cause of hypercalcemia: An important differential to remember

Malignancy often manifests itself as hypercalcaemia, an electrolyte abnormality that can lead to several other systemic consequences. In adult T cell Non- Hodgkins lymphoma, more than half the patients (about 60%) present with symptoms of hypercalcaemia. 1 It is rare in B cell non-hodgkins lymphoma (BNHL), with only 5-8% of cases manifesting with hypercalcaemia. 2 Peripheral T cell lymphomas (PTCL) make up a very small percentage of lymphomas. We present a case of a 46 year old male who initially presented with diffuse abdominal pain and hypercalcemia. He was evaluated for sarcoidosis. Further imaging and a biopsy revealed T-NHL with hypercalcaemia.
