A young patient with cord compression diagnosed as a solitary sacral plasmacytoma: a case report

Abstract

Plasmacytoma is a subgroup of plasma cell neoplasms characterized by localized proliferation of neoplastic plasma cells. It is a rare disease that accounts for only less than 5% of all plasma cell tumours and can present alone or with multiple myeloma. Here, we report a clinical case of unusual presentation, in which solitary sacral plasmacytoma of a previously well young woman presented with bilateral lower limb numbness. She was found to have a sacral-originated tumour, which was later diagnosed as a solitary sacral plasmacytoma with the help of imaging and histological evaluation, along with the absence of the end organ damage.
