Spinal Lesions as Clinical Manifestations of Plasma Cell Neoplasia

Resection of Thoracic Plasmacytoma and Corpectomy Through the Anterolateral Thoracic Approach: A Case Report

This case report details the case of a 57-year-old male who initially manifested low back pain radiating from the lumbar region to the left leg. Progressive symptoms included paresthesia on the plantar surfaces of both feet and gait instability attributed to weakness in the pelvic limbs. Computed tomography imaging revealed osteolytic lesions in the T9, T10, and T11 vertebral bodies, resulting in compression of the spinal cord. Subsequent contrast-enhanced magnetic resonance imaging validated these findings, confirming the presence of an extradural tumor. In accordance with the Spinal Instability Neoplastic Score (SINS), the case was categorized as indicative of potential spinal instability. Consequently, a surgical intervention was performed to excise the lesion. Thus, the role of SINS played a pivotal role in guiding the decision-making process for the chosen treatment modality.

A Case Report of Plasmacytoma in a 28-Year-Old Patient: Bridging the Age Gap in a Rare Presentation

Plasmacytoma, an uncommon malignancy originating from plasma cells, predominantly manifests in the elderly demographic. However, its incidence among young adults remains infrequent. Herein, we present a case involving a 28-year-old young adult diagnosed with solitary bone plasmacytoma. The patient presented with acute exacerbation of chronic lower back pain of two years, which, upon hospitalization, was attributed to a lumbar spine compression fracture. Comprehensive blood analysis, imaging studies, and pathology assessments suggested the likelihood of solitary plasmacytoma, devoid of indicators characteristic of multiple myeloma (MM). The patient was given symptomatic treatment and underwent surgical spine decompression, followed by the commencement of radiation therapy to address the malignancy. Subsequent to radiotherapeutic intervention, a noteworthy amelioration in pain and overall condition was observed. This case report assumes importance due to the insight it provides into the natural progression of solitary plasmacytoma. Patients with pathological fractures warrant thorough assessment for solitary plasmacytoma, necessitating vigilant monitoring for its potential evolution into MM. This case serves as a pertinent illustration of the need to expand our existing knowledge of solitary bone plasmacytoma, moving beyond the conventional notion that it predominantly afflicts the elderly population.
