Abstract

INTRODUCTION:

Papillary thyroid cancer (PTC) is the most frequent histological subtype of thyroid cancer. The lymph node metastasis is found in a high proportion of patients with PTC at the time of surgery. In contrast, tuberculous lymphadenitis remains a common cause of cervical lymphadenopathy in Asian countries.

PRESENTATION OF CASE:

We present a 60-year-old woman with coexistence of papillary thyroid carcinoma (PTC) and cervical tuberculous lymphadenitis and to show the usefulness of fine-needle aspiration biopsy (FNAB) and quantiferon testing to distinguish a lymph node metastasis of PTC from tuberculous lymphadenitis.

DISCUSSION:

FNAB and quantiferon testing are useful tools to check if enlargement of cervical lymph node is due to tuberculous infection, and a surgical plan should be carefully determined to avoid unnecessary surgical complications and the spread of tuberculous infection.

CONCLUSION:

The coexistence of cervical tuberculosis should be considered in the etiology of an enlarged lymph node for patients with PTC.
