摘要:
Background: Liposarcomas originating in the supraclavicular fossa are exceptionally rare, with only a few documented cases in the medical literature. Methods: We present a unique case involving a remarkably large indolent, atypical lipomatous tumor or well-differentiated liposarcoma situated in the right supraclavicular region, measuring 18 cm x 18 cm x 17 cm. To our knowledge, this represents the largest liposarcoma found in the supraclavicular fossa reported in the literature. This unique case highlights the effective management of a remarkably large supraclavicular liposarcoma through complete surgical resection. Result and Conclusion: Our findings further support the existing consensus that complete surgical removal is often curative for well-differentiated liposarcoma.
