High frequency of incidental diagnosis of extrathyroidal neoplastic diseases at the fine-needle aspiration biopsy of laterocervical lymph nodes in patients with thyroid nodules.
This study was undertaken to evaluate the frequency of the incidental diagnosis of extrathyroidal lymph node diseases at ultrasound-guided fine-needle aspiration biopsy/cytology (FNAB/C) being done to check the presence of metastatic thyroid cancer in 30 subjects with thyroid nodule (TN) and enlarged cervical lymph nodes (CLN). The patients in whom cytology suggested the presence of malignancy in the TN or in the CLN underwent surgical removal for histologic diagnosis. The spectrum of diseases revealed by this survey included: (1) 10 benign diseases including 1 case of Piringer-Kuchinka lymphadenitis with benign TN; (2) 10 metastatic thyroid cancers (2 anaplastic and 8 papillary cancers); (3) 3 benign TN associated with metastatic invasion of cervical lymph nodes from lung (2 cases) and breast (1 case) cancer; (4) 1 Hodgkin's lymphoma of the cervical lymph nodes with hyperplastic TN; (5) 3 nodal lymphomas with benign thyroid nodule and 2 cases of thyroid lymphoma with nodal invasion; and (6) 1 nodal sarcoidosis with benign TN. The results of this study demonstrate that important neoplastic and hematologic diseases affecting the cervical lymph nodes may frequently be incidentally detected using ultrasonography (US) and FNAB/C in the diagnostic procedure for thyroid nodule.
