Objective: This report serves to showcase four cases of rare, malignant primary neoplasms of the anterior chest wall [chondrosarcoma and basal cell carcinoma (BCC)] that thoracic surgeons may encounter, and different approaches to complex reconstruction that may be necessary following resection. Background: Approximately 60% of the anterior chest wall neoplasms are malignant. The most common types of primary sternal tumors are chondrosarcoma and osteosarcoma. While guidelines for resection of these tumors have been previously described in the literature, guidelines regarding reconstructive techniques of the subsequent large defects are infrequently demonstrated. Methods: The medical records of four adult patients with primary chest wall tumors who underwent resection of the sternum from October 2016 to March 2021 were retrospectively reviewed. Radical resection with tumor-free surgical margins offers the best chance for survival, but results in a wide full-thickness defect. Hence, closure of the anterior chest wall defect with skeletal reconstruction is an essential step of the procedure and allows us to highlight surgical techniques and materials that have been used over recent years. Methods described herein include skeletal reconstruction with various hardware or allograft, as well as defect coverage using regional flaps, free tissue transfer, and mesh. Conclusions: Primary chest wall tumors of the sternum are an extremely rare diagnosis with a high malignancy rate. Full-thickness radical en-bloc resection is the most effective treatment option. Subsequent reconstruction of a wide chest wall defect is the most challenging aspect, though crucial in the preservation of the rigidity of the chest wall and protection of underlying structures. Different techniques and materials have been described without clear guidelines in treatment approaches; this paper serves to delineate and describe techniques that achieved successful outcomes.
