Papillary thyroid cancer coexisting with thyroid tuberculosis: A case report.

The current study presents the case of a 56-year-old female, with thyroid nodules showing signs of malignancy under B-mode ultrasonography, who was admitted to Shaoxing People's Hospital. A histopathological examination revealed the coexistence of papillary thyroid cancer (PTC) and thyroid tuberculosis (TB). A total thyroidectomy and selective neck dissection (left side, levels III, IV and VI) were performed. This report presents a rare case showing the malignant growth of thyroid nodules and the development of thyroid TB, which implicates the possible role of mycobacterial infection in the tumorigenesis of PTC.
