We present a case of multifocal plasmacytoma, one of the rarest hematological malignancies, with an unusual presentation of cervical myelopathy. A 60-year-old male presented with features of cervicalgia and radiculomyelopathy. There was a history of significant weight loss over 2 months with no sphincter involvement. Neurological examination showed spastic quadriparesis with extensor plantars. Radiological workup showed multiple lytic lesions from C3 to C6 with cord compression and myelomalacic changes. The patient underwent three-level corpectomy (C5–C7) with cord decompression. Reconstruction was done with an expandable titanium cage, and anterior cervical plating from C4 to T1 was done. The histopathology and immunohistochemistry markers enabled in clinching this rare diagnosis of multifocal plasmacytoma. It is essential to distinguish early between various entities among plasmacytoma as each one has a different clinical course and prognosis. Multiple solitary plasmacytoma presenting de novo with cord compression and myelopathy is an extremely rare presentation. [ABSTRACT FROM AUTHOR]
