“…Extramedullary plasmacytoma occurring in the retroperitoneum was quite rare. In our investigation, we found only one case of solitary extramedullary plasmacytoma in the retroperitoneum reported in the English literature [10].

Solitary extramedullary plasmacytoma is an uncommon neoplasm and occurs most frequently in the upper respiratory tract. Herein, we reported a solitary extramedullary plasmacytoma in the retroperitoneum. A 28-year-old man presented with obstructive jaundice and a retroperitoneal tumor. Ultrasound-guided biopsy confirmed that the lesion was a plasma cell neoplasm. A detailed investigation showed that no other sites were involved. The tumor got a moderate reduction following local irradiation, and a complete remission was achieved after 12 courses of adjuvant chemotherapy. Therefore, the possibility of a solitary extramedullary plasmacytoma should be considered in the differential diagnosis of obstructive jaundice without a history of multiple myeloma. Am. J.

“…The unusual feature of disease progression in our case manifested as multiple huge extramedullary retroperitoneal masses, which have not been reported before in the literature. Only a few cases of retroperitoneal plasmacytomas have been reported to date [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. All of these were primary retroperitoneal tumors (extramedullary plasmacytomas) with no bony lesions on skeletal survey.…”

Solitary bone plasmacytomas and plasma cell myeloma are clonal proliferations of plasma cells. Many patients with solitary bone plasmacytomas develop plasma cell myeloma on follow-up. We present a case of a 70-year-old man who presented with fracture and a lytic lesion in the subtrochanteric region of the left femur and was assigned a diagnosis of solitary bone plasmacytoma. He received local curative radiotherapy. However, 4 months later his serum M protein and β2-microglobulin levels increased to 2.31 g/dL and 5.965 mg/L, respectively. He complained of abdominal fullness and constipation. Ultrasound and non-contrast CT imaging revealed multiple retroperitoneal masses. Colonoscopic examination was normal. Biopsy of the a retroperitoneal mass confirmed it to be a plasmacytoma. Repeat hemogram, blood urea, serum creatinine, skeletal survey, and bone marrow examination revealed no abnormalities. This is an unusual presentation of plasma cell myeloma, which manifested as multiple huge extramedullary retroperitoneal masses and arose from a solitary bone plasmacytoma, without related end organ or tissue impairment and bone marrow plasmacytosis. The patient succumbed to his disease 8 months after the appearance of the retroperitoneal masses. This case highlights the importance of close monitoring of patients diagnosed with solitary bone plasmacytoma with increased serum M protein and serum β2-microglobulin levels, so that early therapy can be instituted to prevent conversion to plasma cell myeloma.
