Liposarcoma of the Thoracic Wall: Report of an Unusual Case

Liposarcoma of the thoracic wall is a rare malignant soft tissue neoplasm characterized by the proliferation of atypical adipose cells. It poses diagnostic and therapeutic challenges due to its low incidence and the anatomical complexity of the region. We report the case of an adult patient with a progressively enlarging thoracic mass, without systemic symptoms, diagnosed by imaging studies and confirmed by biopsy as a well-differentiated liposarcoma. Treatment consisted of complete surgical resection of the tumor with negative margins, resulting in a favorable postoperative course without complications. Histopathology confirmed the absence of high-grade features, predicting a relatively good prognosis. This case highlights the importance of a multidisciplinary approach and close follow-up to prevent recurrence, emphasizing that although uncommon, thoracic wall liposarcoma can be successfully managed surgically in specialized centers.
