OLIVEIRA, Tiago et al. Multiple Myeloma Involvement of the Pancreas: A Case Report of Pancreatic Extramedullary Plasmacytomas Causing Obstructive Jaundice. Acta Radiol Port [online]. 2022, vol.34, n.3, pp.20-22.  Epub 30-Dez-2022. ISSN 2183-1351.  https://doi.org/10.25748/arp.26954.

Extramedullary plasmacytomas are rare tumors that can occur either as primary lesions or as a manifestation of multiple myeloma.

Pancreatic involvement by plasma cell myeloma is very rare, accounting for less than 0.1% of pancreatic masses.

Radiological findings are not specific. The most typical finding of pancreatic plasmacytoma on computed tomography has been reported as the presence of a focal multilobulated mass with homogeneous contrast enhancement.

This is a case report of a 74-year-old woman with a previous history of stage III multiple myeloma presented to the emergency department with complaints of abdominal discomfort and painless jaundice. An abdominal ultrasound and computed tomography were performed and revealed a large mass in the topography of the pancreatic head. This mass caused dilatation of the intrahepatic bile ducts and the main bile duct. Subsequently, the patient underwent ultrasound-guided core biopsy of the pancreatic lesion, and the histological analysis of the specimen confirmed the diagnosis of pancreatic plasmacytoma.

The purpose of this article is to present a very rare case of pancreatic extramedullary plasmacytomas, describe its epidemiology and clinical features, as well as illustrate its imaging findings.
