Primary cavernous hemangioma of the thyroid gland.

A 78-year-old euthyroid patient presented for evaluation of a symptomatic, slowly growing neck mass. Ultrasound scan revealed a multinodular goiter and a hypoechoic nodule of the right thyroid lobe. Total thyroidectomy was performed and the lesion was completely excised. Definite diagnosis was obtained after histological examination of the surgical specimen. Cavernous hemangiomas of the thyroid gland are infrequent lesions which may escape diagnosis preoperatively. An effort should be made not to rupture these lesions in order to ensure a bloodless procedure.
