Multiple plasmocytoma - a rare case of three atypical presentations

Abstract

Introduction: The solitary plasmocytoma represents less than 5% of all plasma cell neoplasms. The multiple plasmocytoma is 20 times rarer than solitary plasmocytoma. Progression to multiple myeloma is common. Methods: Case study Results: We report a very rare case of multiple plasmocytoma developed in the bone and two atypical sites - renal and gastric. The patient was treated with radiotherapy, surgery and chemotherapy. The case is presented due to its rarity. Conclusion: The high risk of a progression towards a multiple myeloma justifies a comprehensive initial assessment and regular monitoring of all plasmocytomas. The management of a patient with multiple plasmocytomas will be determined by the sensitivity and the site of the tumor.
