Neurogenic Tumors of the Thyroid Gland

Benign nonepithelial tumors of the thyroid gland are very rare and include lesions such as vascular tumors, smooth muscle tumors and neurogenic tumors. Schwannoma and neurofibroma are benign neoplasms of mesenchymal origin which frequently occur in the head and neck, but their origin within the thyroid gland has rarely been reported. Recently, we encountered two cases of neurogenic tumor of thyroid gland(l schwannoma, 1 neurofibroma) and report them to support the view that Schwannoma and neurofibroma may occur in thyroid gland, which is an unusual site, and are recognizable entities.
