This case report has described a case of papillary carcinoma of thyroglossal duct in a young male. This patient was admitted with a mass in the anterior neck for 2 years. Preoperative Bultrasonography, CT and MR showed a subcutaneous cystic mass with irregular calcification shadow in the central region of the neck without obvious enhancement. Initial diagnosis was thyroglossal duct cyst, and was excised by Sistrunk under general anesthesia. The postoperative pathological examination showed thyroglossal duct cyst combined with thyroid papillary carcinoma, which was confirmed by immunohistochemistry as thyroglossal duct papillary carcinoma.

OBJECTIVE: This study was to evaluate the patterns of central lymph nodes metastasis, by analyzing the results of surgery in clinical NO (cNO) papillary thyroid carcinoma (PTC). METHOD: We retrospectively studied the effect of surgical treatment among 123 cN0 PTC patients. All the patients underwent central lymph node dissection; 47 patients underwent ipsilateral neck dissection and 9 patients underwent bilateral neck dissection. RE- SULT: Seventy-eight cases (63.4%)were found positive central lymph node, which included 34 cases (27.6%) bilateral positive central lymph node. Central lymph node metastases correlated with age < 45 years, extrathyroidal extension, surrounding tissue invasion and tumor size grade (P < 0.05), were the independent risk factors of central lymph node metastasis. CONCLUSION Age < 45 years, extrathyroidal extension and surrounding tissue invasion were the independent risk factors of central lymph node metastasis. For cNo patients with PTC, primary excision as well as central neck dissection was recommended; according to the results of intraoperative frozen and situation, further process were made.

The aim of this study was to review the literature of latent papillary thyroid carcinomas (PTCs) discovered at autopsy and describe the available pathologic and demographic differences from a group of papillary thyroid microcarcinomas (PTMCs) the reported in a previous publication. We searched the PubMed for published articles describing latent thyroid carcinomas detected at autopsy. Meta-analysis was performed to identify differences between the clinicopathologic features of PTMCs analyzed previously in our institution (Group I) and those of latent PTCs described in autopsy studies (Group II). We identified 1,355 patients with PTMC (Group I) and 989 with latent PTCs (Group II). Mean patient age was 47.3 yr in Group I and 64.5 yr in Group II. The male:female ratio was 1:10.9 in Group I and 1:1 in Group II. Most PTMCs (67.6%) were larger than 0.5 cm in size, whereas most latent PTCs were <1-3 mm in diameter. The rates of multifocality were 24.7% in Group I and 30.5% in Group II, and the rates of cervical lymph node metastasis were 33.4% in Group I and 10.0% in Group II. Currently available data indicated that clinically evident PTMCs differ from latent PTCs detected at autopsy. Therefore, these two entities should be regarded as different.

A 56 years old female was admitted to our department with complaint of a painless cervical mass. Clinical feature:there was a painless mass above left lobe of thyroid gland, which was about 3.0 cm x 2.5 cm in size, and could move with swallowing action. B-mode ultrasound features: there was a solid mass in left lobe of thyroid gland, which was about 3.2 cm. Nodule was found in isthmus, accompanied with lymphadenovarix on the left neck possibly be MCA. fT3: 4.64 pmol/L, fT4:16.56 pmol/L,TSH:3.74 mIU/L, anti-TG:17.75 U/ml, anti-TPO:40.77 U/ml. Pathological result of the neoplasm: papillocarcinoma. Clinical diagnosis: papillary thyroid carcinoma.

OBJECTIVETo compare the size of papillary thyroid carcinoma on ultrasonography(US)and the actual size measured during histological examination and to discuss the potential causes of such discrepancy.

METHODSA total of 148 patients with histologically confirmed papillary thyroid carcinoma underwent thyroid surgery in our center from December 2012 to May 2013. Patients were stratified based on the size,morphology,margin,cystic component,and presence of Hashimoto's disease to compare the discrepancy of the US and pathalogical measurements.

RESULTSThe mean sizes of the nodules measured by US and pathology were(1.58±0.94)cm and(1.33±0.84)cm,respectively(P=0.000). In 70.9%(105/148)of the nodules,the sizes measured by US were larger than those measured by pathology. In 17.6%(26/148)of the nodules,the sizes measured by US were smaller than those measured by pathology. In 1.1-1.4 cm size subgroup,the difference between mean ultrasound diameter and pathologic diameter was not significant [(1.21±0.11)cm vs.(1.11±0.32)cm,P=0.062]. In 0.1-1.0 cm size subgroup,the mean sizes of the nodules measured by US and pathology were(0.75±0.19)cm and(0.62±0.23)cm,respectively(P=0.000). In ≥1.5 cm size subgroup,the mean sizes of the nodules measured by US and pathology were(2.48±0.70)cm and(2.03±0.81)cm(P=0.000).

CONCLUSIONSThere is a significant discrepancy between US and pathologic size measurements for papillary thyroid carcinoma. However,for nodules sized 1.1-1.4 cm,the ultrasound and pathologic measurements are more likely to be consistent.
