Reconstruction with Supraclavicular Artery Island Flap for an Undifferentiated Pleomorphic Sarcoma of the Head and Neck: A Case Report

Undifferentiated pleomorphic sarcoma (UPS) is a rare, high-grade malignant mesenchymal tumor of the head and neck region. In this case report, we present a 34-year-old male patient who underwent surgical resection for a large UPS located on the right side of the neck, followed by reconstruction using a supraclavicular artery island flap (SCAIF). After evaluation of the mass through physical examination and imaging modalities (MRI, CT, and PET-CT), an incisional biopsy confirmed the diagnosis. Surgical management included excision of the mass and a modified radical neck dissection. The resulting large cutaneous defect was reconstructed using a SCAIF. The postoperative course was uneventful, and the patient was discharged on the 15th postoperative day. Histopathological examination confirmed the diagnosis of undifferentiated pleomorphic sarcoma, and the patient was subsequently treated with adjuvant radiotherapy and concurrent chemotherapy. This case highlights not only the diagnostic and therapeutic approach to UPS but also demonstrates that SCAIF is a reliable and effective option for the reconstruction of extensive soft tissue defects in the head and neck region.
