Case reportExtramedullary plasmacytoma of the pancreas and jejunum
Introduction
Plasma cell neoplasms may present as multiple myeloma, solitary myeloma of the bone, plasma cell leukemia, or as extramedullary plasmacytoma (EMP) [1], [2]. Extramedullary plasmacytoma of the pancreas and gastrointestinal tract, either isolated or in association with multiple myeloma, is extremely rare [3], [4], [5], [6]. We report a very rare case of pancreatic and jejunal plasmacytoma in a single patient with known multiple myeloma with emphasis on computed tomographic (CT) findings. Such concurrence has not been reported before in radiology literature and, to the best of our knowledge, CT imaging features of jejunal involvement have not been described before.

Case report
A 59-year-old white male patient with light chain myeloma (IgA-K type) diagnosed by fine-needle aspiration of sternal mass 1 year ago was admitted with a rapid increase in the size of this mass and excruciating pain for radiation treatment and pain management. Multiple myeloma survey radiographs done at the time of initial diagnosis had also demonstrated additional bone involvement with lytic lesions in bilateral distal clavicles, right iliac bone, and right proximal femur.

Discussion
Plasma cell neoplasms may present as multiple myeloma, solitary myeloma of the bone, plasma cell leukemia, or as EMP [1], [2]. Extramedullary plasmacytomas are seen and can arise anywhere in the body, although the vast majority of cases occur in the head and neck with 80% occurring in the nasal cavity, paranasal sinuses, and upper airways. Involvement of the gastrointestinal tract is reported in approximately 10% of cases, most of which involve the liver and spleen [3], [4], [5], [6]. Very few

Initial (and incidental) diagnosis of plasma cell neoplasm in the liver and gastrointestinal tract – Lessons to be learnt from two cases and literature review
2022, Human Pathology ReportsCitation Excerpt :Plasma cell neoplasms (PCN) are a heterogeneous group of mature B-cell-derived neoplasms that include, but are not limited to plasma cell myeloma (PCM), defined by the presence of a clonal plasma cell proliferation that exceeds greater than 10% in the bone marrow plus evidence of end-organ damage or another biomarker of malignancy, or the finding of a plasmacytoma, a proliferation of monoclonal plasma cells that grow in the axial skeleton or in the soft tissues [1,2].
Solitary Extramedullary Multiple Myeloma Presenting with Small Bowel Obstruction
2016, Journal of Emergency MedicineCitation Excerpt :The small bowel, especially the ileum, is the most common site of EM (5). Fewer than 20 cases of solitary jejunal EM have been reported in the literature (5–10). To the best of our knowledge, only 2 of them reported small bowel obstruction as a complication (8,9).
