Abstract:
Among 527 patients with thyroid disease who underwent surgery at our hospital during a 20-year period, 2 (0.4%) had tuberculous thyroiditis mimicking carcinoma. The first patient was a 44-year-old man with a solitary thyroid nodule and the second was a 24-year old man with a thyroid abscess. The unexpected diagnosis was made postoperatively and was based on histological findings in both patients. No primary focus was found elsewhere in either patient, and both responded to antituberculous chemotherapy. Although the diagnosis is usually based on examination of resected specimens, recent reports indicate that find-needle aspiration cytology is a cost-effective technique of diagnosing thyroid tuberculosis. A review of 35 cases reported in the English literature is also discussed.
