- This is a case of a 30-year-old man who was referred to our hospital for evaluation of a rapidly growing tumor in the left thyroid gland. It was palpated 2 weeks ago. But it was growing fast. A 4×3 cm mass was palpated in the left thyroid gland. Our impression was anaplastic thyroid carcinoma. Computed tomography finding indicated a thyroid malignant tumor and cytology result suggested spindle cell neoplasm. A lower anterior neck mass was resected and final histopathological result turns out to be a rhabdomyosarcoma (RMS). Although cervical RMS is very rare in adults, it has to be included for the differential diagnosis for the rapidly growing mass at thyroid gland.
