Metastatic papillary thyroid carcinoma with absence of tumor focus in thyroid gland

چکیده
BACKGROUND Papillary thyroid carcinoma presenting as isolated cervical lymphadenopathy with clinically and histologically normal thyroid gland is rarely reported. CASE REPORT We report a case of 31 years old female who presented with a left cervical mass and clinically normal thyroid gland. After inconclusive FANC, excision biopsy of her cervical lymph nodes revealed metastatic papillary thyroid carcinoma. The patient subsequently underwent total thyroidectomy with bilateral lymph node dissection. Interestingly pathological examination showed no primary carcinoma in the gland. Postoperative radioactive iodine scan revealed no other metastasis. CONCLUSIONS Total thyroidectomy is the next best step despite clinically and radiologically normal appearing thyroid gland once cervical lymph nodes are proven to be metastatic in nature followed by a RAI therapy to treat occult foci of PTC.

Different markers used for determination of prognosis and VEGFR is one of them. The aim of present study was to determine the expression of Vascular Endothelial Growth Factor Receptor (VEGFR) as a prognostic marker in papillary carcinoma...

Squamous cell differentiation (SCD) may occur in papillary thyroid carcinoma (PTC) only at metastatic sites. We have studied cytokeratin CK5/6 and P63 along with TTF1 (thyroid transcription factor 1) and B-Raf (V-Raf murine sarcoma viral oncogene homolog B1) immunohistochemical expression in neck lymph node metastases of thyroid PTC showing SCD. The patient (21-years) presented wit...
