Giant Interpectoral Lipoma Causing Venous Thoracic Outlet Syndrome: A Rare Case Presentation
Abstract
Summary:. Lipomas are the most prevalent type of benign soft tissue tumors, primarily composed of adipocytes, and typically remain asymptomatic unless they reach a significant size. Although giant lipomas are infrequent, their occurrence on the chest wall, particularly in the interpectoral region, is exceedingly rare. We present a unique case of a 48-year-old man with a massive interpectoral lipoma measuring 19.4 × 12.9 × 9.4 cm, which resulted in venous thoracic outlet syndrome by compressing the subclavian vein. This case highlights the clinical challenges in diagnosing deep-seated chest wall lipomas and underscores the necessity of considering thoracic outlet syndrome as a potential complication, even in the absence of direct neural or arterial compression. The presentation of thoracic outlet syndrome can vary, and a comprehensive evaluation is imperative for accurate diagnosis and management.
