A 75-year-old man underwent staging EUS for early esophageal neoplasia. A 20 mm heterogeneous mass in the pancreatic body was found, with non-diagnostic fine needle biopsy (FNB). MRI showed a 60 mm mass, suggestive of neuroendocrine tumour or lymphoproliferative process. Repeated EUS tissue acquisition demonstrated cells CD138+and kappa light chain. Multiple myeloma was ruled out. Finally, diagnosis of primary pancreatic plasmacytoma (PPP) was made and radiotherapy was started with a good response.

Only 5 cases of PPP have been reported to date. EUS-FNB is essential for diagnosis, demonstrating tissue infiltration by monoclonal plasma cells.
