Primary cavernous haemangioma of the thyroid - a case report.

Primary thyroid haemangioma is extremely rare, with only countable cases having been previously reported. We are reporting a case of 38-year-old male with history of diffuse thyroid swelling in front of the neck, which was firm to hard in consistency. Ultrasonography (USG) displayed an enlarged left thyroid with anechoic / isoechoic nodule and foci of coarse calcification. Preoperative clinical diagnosis of solitary thyroid nodule was made. Fine Needle Aspiration Cytology (FNAC) was inconclusive, due to bloody aspirate. Left hemi-thyroidectomy was performed. Haemangioma was diagnosed, based on histopathological examination findings. Surgical excision would be the treatment of choice, which provides a good prognosis.
