Extramedullary plasmacytomas are rare, constituting to about 5% of plasma cell neoplasms. Pancreatic involvement is uncommon constituting to about 2.3%. Localised solitary plasmacytomas has a good response to radiation. When they are associated with pre-existing multiple myeloma, their prognosis is poor. A case of plasmacytoma of pancreas presenting with obstructive jaundice preceding plasma cell leukaemia is presented here. The lesion was misdiagnosed by fine needle aspiration cytology as neuroendocrine neoplasm. The patient did not present with symptoms of myeloma initially. The present case highlights the significance of considering other causes of pancreatic mass than primary carcinomas.
