Differentiated posterior cervical liposarcoma with carcinoid: report of a case

Liposarcoma most commonly arises in the retroperitoneum and lower extremities. Liposarcoma of the head and neck region is a rare and potentially life-threatening malignancy. Those originating in the right retrocervical space cause special diagnostic and therapeutic difficulties. In present report, a case of differentiated liposarcoma of the right cervical region with intestinal carcinoid is reported. The tumor continued to grow slowly over 3 years before a definitive diagnosis was established. Extended extirpation of the tumor and modified radical neck dissection, postoperative radiotherapy followed by chemotherapy were performed and proved to be efficacious in that no recurrence was observed for 2 years. Recommendations for earlier and correct diagnosis and treatment of this rare neoplasm are discussed.
