A heart transplant patient developed a recurrent left chest mass. Surgical resection revealed a high-grade osteosarcoma, a rare primary bone cancer.
Area of Science:
- Cardiology
- Oncology
- Thoracic Surgery
Background:
- A 69-year-old female with a 16-year history of heart transplantation presented with a significant left chest mass.
- The patient reported substantial weight loss and progressive shortness of breath.
Observation:
- Initial imaging revealed a large, complex cystic mass in the left chest.
- CT-guided aspiration cytology was negative for malignancy.
- Despite initial negative findings, a recurrence of the pleural mass was observed three months later.
Findings:
- The recurrent mass required surgical exploration via video-assisted thoracotomy and subsequent thoracotomy for complete resection.
- Final pathology confirmed the mass as a high-grade osteosarcoma.
Implications:
- This case highlights the importance of considering rare malignancies in transplant recipients with unexplained masses.
- Osteosarcoma, typically a bone tumor, can rarely present as a primary extraskeletal or pleural mass.
- Multidisciplinary management is crucial for diagnosis and treatment of such complex cases.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Spongy Bone
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...
