Abstract：Chest wall tumors are a type of tumor disease that occur in the skeletal tissue and deep soft tissues of the chest wall, commonly found in the sternum and costal cartilage [1]. Chest wall tumors include various tumor-like lesions and tumors. Relevant studies indicate that the clinical manifestations of this disease are closely related to factors such as tumor size, histological type, location, and duration [2]. The clinical diagnosis of chest wall tumors mainly relies on clinical examination, imaging examinations, and pathological examination, with pathological examination being the key to confirmation. It can clarify the type and grade of the tumor, providing a basis for the formulation of subsequent treatment plans [3]. Atypical lipomatous tumor is an intermediate, locally aggressive adipocytic tumor, accounting for 1% to 3% of all chest wall tumors. It presents as a well-defined lobulated mass, and depending on the content of fat cells, fibrous components, and mucoid components, the mass may show different colors ranging from yellow to white. Larger lesions often have necrotic areas [4-5]. Giant atypical lipomatous tumor of the chest wall is extremely rare in clinical practice. This article summarizes the diagnostic and treatment experience of one case of giant atypical lipomatous tumor of the chest wall treated at Hainan Provincial People's Hospital, Affiliated Hospital of Hainan Medical University, in order to provide a basis for clinical diagnosis and treatment.
