A 28-year-old woman was found to have a hypoechoic mass in the supero-posterior portion of the thyroid on ultrasonography. It was not diagnosed by aspiration biopsy, however, and tumor resection was performed on May 16, 1997. The tumor originated to the left lateral wall of the hypopharynx. It showed eosinophilic granules in the cytoplasm and stained positive for S-100 protain. A diagnosis of granular cell tumor (GCT) was made histologically. Cervical GCT is rarely reported in Japan. Complete excision is the preferred treatment for benign GCT, because benign GCT can undergo malignant change.
