Well-Differentiated Liposarcoma in the Left Face

Liposarcoma is the most prevalent malignant neoplasm originating from mesenchymal tissues, accounting for ~25% of soft tissue sarcomas in adults. It typically occurs in the trunk, limbs, retroperitoneum, and other anatomical regions, while its occurrence in the facial area is relatively rare. Here, the authors present a case involving an Asian male patient who presented to the Department of Dermatology and Cosmetic Surgery at our hospital with a subcutaneous mass located on the left side of the face. After a thorough evaluation, including ultrasonography and additional diagnostic examinations, the lesion was excised completely under local anesthesia. The patient had the sutures removed 1 week postoperatively, and regular follow-up was conducted for 3 months without signs of recurrence or metastasis. The patient expressed satisfaction with the outcome.
