Hemangioma of the Thyroid

Thyroid hemangioma is very rare, and only a few cases have previously been reported. We encountered a patient with thyroid hemangioma diagnosed after surgery. Case Report A 71-year-old woman visited our hospital with a mass in the left thyroid region. A 5-cm, elastic mass of the thyroid was palpable in the left anterior neck. On cytology by fine-needle aspiration (FNA), the specimen mainly contained blood components without apparent atypical cells. A tumor with abundant blood flow was suspected based on Doppler ultrasonography. Adenomatous goiter was suspected, and subtotal thyroidectomy was performed. A blood clot was present in the tumor, and hemangioma was diagnosed on postoperative histopathological examination. Discussion Preoperative diagnosis of thyroid hemangioma is difficult. However, Doppler ultrasonography and FNA are useful for diagnosis. A differential diagnosis of hemangioma should be considered when blood flow is abundant and only blood components are collected
