ICD-10 Code
C90.20

Localized malignant tumor of plasma cells within a single bone.

Clinical Presentation & Protocol

Patient Usually Complains Of

Patient presents with localized bone pain, most commonly in the axial skeleton, persisting for [Duration]. No constitutional symptoms (B-symptoms) reported. Denies history of multiple myeloma or systemic plasma cell dyscrasia. Pain is described as [Quality: dull/aching/sharp], exacerbated by movement, and not relieved by rest. No neurological deficits or radicular symptoms noted.

Clinical Examination Findings

Localized tenderness noted upon palpation of the affected bone site. No palpable soft tissue mass or overlying skin changes observed. Range of motion at adjacent joints is [Normal/Restricted]. Neurological examination reveals intact sensation and motor strength in the affected extremity. No lymphadenopathy or hepatosplenomegaly detected.

Treatment Protocol

Primary treatment modality is definitive radiotherapy to the involved bone site. Surgical intervention (curettage/stabilization) considered if pathological fracture risk is high or structural integrity is compromised. Close monitoring for progression to Multiple Myeloma via serial serum protein electrophoresis (SPEP), free light chain assays, and periodic imaging (MRI/CT/PET-CT).
