A Case of Liposarcoma Arising in Tracheoesophageal Groove

Liposarcoma is the second most common soft tissue sarcoma in adult, after malignant fi brous histiocytoma. But, the incidence of liposarcoma in the head and neck malignancies is approximately 1.8-6.3%. Primary liposarcoma of the thyroid gland is exceedingly rare with only six previous reports in the English literature. We report a case of liposarcoma in a 61-yearold male who had been misdiagnosed with thyroid nodule and follicular neoplasm suspected in fine needle aspiration cytology. Mass excision of the liposarcoma was performed. During the preoperative evaluation and operation, the author recognized that the tumor had originated not from the thyroid gland, but from the tracheoesophageal groove. The histopathological examination revealed a combination type liposarcoma that was both well differentiated and myxoid. But a paramedian fixation was found in the left vocal cord palsy and injection laryngoplasty was performed. Postoperatively, radiotherapy was given to the neck region. Dur
