Solitary Ovarian Plasmocytoma: A Rare localization of Extramedullary Plasmocytoma. A Case Report

Abstract

Background: Solitary plasmacytoma is a rare malignant neoplasm of plasma cells accounting 5-10% of all plasma cell dyscrasias with extramedullary plasmocytoma in 3- 5%. Their localization in the female genital tract is quite rare, either as solitary plasmacytomas or as part of a disseminated MM. Solitary ovarian plasmocytoma is extremely rare. Case: A 52-year-old woman, presented presented postmenopausal recurring episodes of metrorrhagia with left ovarian mass. She was diagnosed with solitary ovarianplasmocytoma without systemicdisease. The patient underwent complete surgery resection and a full work up to rule out multiple myeloma that objectived a small serum monoclonal protein that had resolved postoperatively. At 17 months of follow-up, the patient is still alive and doing well with no signs of recurrence or progression to mutliple myeloma. Although rare, solitary plasmacytoma of the ovary can occur without any overt symptoms or laboratory abnormalities tests and require prompt and adequate treatment and rigorous monitoring due to their ability to relapse or progress to MM. Complete surgical resection followed by activesurveillance is appropriate.
