We experienced a case of the papillary thyroid carcinoma seen as a huge solid lateral neck mass. The mass grew very slowly over the period of 30years up to 10cm in diameter while relatively well sparing the surrounding tissues. Physical examinations, CT scan, and fine needle aspiration cytology did not reveal any strong suggestions for evidence of malignancy. But it was pathologically diagnosed as metastatic thyroid carcinoma by excisional biopsy. We emphasize that for a large solitary neck mass which persists for several decades, head and neck surgeons should always keep in mind the possibility of metastasis from the malignancy of thyroid gland.

Ovarian cancer is common malignant disease with high mortality in the female. However, lymph node metastasis in the head and neck of ovarian cancer is very rare than in para-aortic, pelvic lymph node. A 49-year-old female patient came to our clinic with a left neck mass. After total thyroidectomy and left selective neck dissection for the cervical neck level II, III, IV, V, VI for ovarian cancer and thyroid cancer, she had already undergone chemotherapy (Paclitaxel+Carboplatin) 18 month ago. CT scan showed only lymph node enlargement in left neck level II. Positron emission tomography-computed tomography (PET-CT) revealed a hypermetabolic lesion in same area but no other hypermetabolic lesion, especially in the pelvic and abdominal cavity. Fine needle aspiration cytology revealed metastatic carcinoma. The serum level of CA-125 was elevated to 43.8U/mL, whereas other tumor markers (CA 19-9, CEA) were in the normal range. She underwent a revision of selective neck lymph node dissection for the cervical neck levels I, II, and III, and on the review of surgical pathology, metastatic carcinoma was suspected. Thus, we performed immunohistochemical staining for the tissue; as a result, it was finally diagnosed as metastatic ovarian cancer (positive for CK7, ER and PR, and negative for CK20). Adjuvant chemotherapy (Paclitaxel+Carboplatin) was planned on the tumor board, and the patient successfully received chemotherapy.

Background: Tuberculous cervical lymphadenitis can be diagnosed by clinical findings, chest X-ray, Mantoux test, but confirmed only by excisional biopsy. The polymerase chain reaction(PCR) is now widely applied to test very small amount of pathogen and would be used to detect Mycobacterium tuberculosis in biopsied tissues and fine needle aspirates. Method: We carried out the PCR using IS-1 and IS-2 primers in 16 samples from tuberculous cervical lymphadenitis patients, and 13 samples from non-tuberculous cervical lymphadenopathy patients. Acid fast staining and culture for Mycobacterium were all negative. Results: All of 8 pathologically confirmed tuberculous cervical lymphadenitis samples showed positive PCR results, and of 5/8 clinically diagnosed samples were positive. None of 6 pathologically excluded samples were positive, and among 7 clinically undiagnosed samples 2 showed positive PCR results. Conclusion: In patients with suspected tuberculous cervical lymphadenitis, PCR could be used to detect Mycobacterium tuberculosis using biopsied tissues and even fine needle aspirates with good sensitivity and specificity.
