Isolated plasmacytoma of the sternal stalk: a case report and review of the literature

Background: Isolated plasmacytoma of bone is a malignant neoplasm of haematologic origin with a low incidence and a tendency to progress to multiple myeloma, and surgical treatment may improve patient survival. Case presentation: We review the case of a 77-year-old man with isolated plasmacytoma of the sternal stalk whose main symptom was pain in the anterior chest wall, which was severe and severely interfered with life. He was treated through extended radical resection of the sternal stalk tumour, including bilateral partial rib cartilage resection, bilateral clavicle head resection, cervical lymph node dissection, and thoracic reconstruction. He recovered well after surgery and was satisfied with the outcome. Conclusion: Extended radical sternoplasty and rib plate reconstruction in the thorax is an effective surgical method for the treatment of isolated plasmacytoma of the sternal stalk and can effectively relieve painful symptoms and improve quality of life; moreover, this approach may improve the survival rate of such patients.
