Extramedullary plasmacytoma is a rare plasma cell neoplasm that involves the ovary
very rarely. Here, I report a case of primary ovarian plasmacytoma in a 42-year-old
patient. The patient presented with abdominal distention, and workup showed a left
ovarian mass (6.5 cm × 8 cm) with marked ascites. The patient had a hysterectomy with
bilateral salpingo-oophorectomy. Histopathologic, immunohistochemical, bone marrow
examination, and other relevant examinations established the diagnosis of primary
ovarian plasmacytoma with kappa light chain restriction. No evidence of malignancy
in the omentum and ascitic fluid was detected. The patient did not need postoperative
chemotherapy or radiotherapy, and 6-month follow-up was uneventful. Due to the scarcity
of information on these extremely rare tumors with abdominal masses, the diagnosis
should be considered if complete surgical resection is achieved and no evidence of
multiple myeloma is found.
Key-words:
Extramedullary plasmacytoma - extramedullary plasmacytoma - ovary - plasmacytoma -
primary neoplasm
