Which are examples of benign soft tissue tumors of the chest wall?

• A. Lipoma, cavernous hemangioma, lymphangioma
• B. Osteosarcoma, chondrosarcoma
• C. Ewing sarcoma
• D. Lymph node metastasis

Answer: (A)

Benign soft tissue chest wall tumors come from non-bony tissues such as fat, blood vessels, or lymphatics and typically present as slow-growing, well-defined masses in the soft tissues over the chest wall. Lipoma is a benign tumor of mature fat cells. Cavernous hemangioma consists of large vascular spaces lined by endothelium. Lymphangioma is a benign malformation of lymphatic channels. These three arise in soft tissue, are usually non-aggressive, and do not invade or metastasize, which is why they are considered benign soft tissue tumors of the chest wall. In contrast, osteosarcoma and chondrosarcoma are malignant bone/cartilage tumors, Ewing sarcoma is a malignant small round blue cell tumor often involving the bone, and lymph node metastasis represents spread rather than a primary benign chest wall soft tissue tumor.
