The study presents the case of a 37-year-old female expatriate who was referred with a neck swelling and was managed further in Tawam Hospital, Al Ain. Initial ultrasonography and fine needle aspiration cytology from the right thyroid nodule confirmed papillary carcinoma of thyroid Bethesda type 6 and fine needle aspiration cytology from the right mid jugular lymph node proved metastasis from the primary. Further evaluation by CT scan neck with contrast and a total thyroidectomy and bilateral selective neck dissection was done. Histopathology confirmed classic papillary thyroid carcinoma with metastasis and caseating granulomatous inflammation in a section of thyroid and few lymph nodes. This case report is a rare presentation of papillary thyroid carcinoma with caseating granulomatous inflammation and presents a challenge for further management and a possible role of caseating granulomatous infection in the tumorigenesis of Papillary thyroid carcinoma.
