Primary chest wall tumors

The differential diagnosis of chest wall tumors is diverse, including both benign and malignant lesions (primary and malignant), local extension of adjacent disease, and local manifestations of infectious and inflammatory processes. Primary chest wall tumors are best classified by their primary component: soft tissue or bone. Work-up consists of a thorough history, physical examination and imaging to best assess location, size, composition, association with surrounding structures, and evidence of any soft tissue component. Biopsies are often required, especially for soft tissue masses. Treatment depends on histological subtype and location, but may include chemotherapy and radiotherapy in addition to surgical resection.
