Primary Schwannoma of the Thyroid Gland in a 71-Year-Old Woman: A Case Report.

Schwann cells in the body's nerve sheath can develop into benign tumors known as schwannomas. While thyroid gland schwannomas are uncommon and are rarely documented in the literature, they are less unusual than those appearing in the head and neck region. The rare nature of schwannomas connected to the thyroid gland adds to the difficulty in detecting them prior to surgery. At present, the most popular form of treatment for thyroid schwannomas is surgical resection, which is considered to be curative. A mass excision or lobectomy has a favorable prognosis, few postoperative complications, and a low risk of tumor recurrence. This paper reports the case of a 71-year-old woman who presented with left neck swelling that had been increasing in size over a number of years. An ultrasonography examination revealed multiple bilateral thyroid nodules with high vascularity. The patient's right thyroid lobe exhibited benign nodular hyperplasia while the thyroid tissue of the isthmus exhibited benign nodular hyperplasia and schwannoma. Following the diagnosis, the patient's mass was successfully surgically removed.
