Familial Adenomatous Polyposis (FAP) is a multi-tumoral syndrome that includes neoplasms in the duodenum, brain, pancreas and thyroid. The Cribriform Morular Variant (CMV) is a rare form of Papillary Thyroid Cancer seen in patients with FAP. Presented here is a 32 year old female who initially presented with an anterior neck mass followed years later by a rectal mass. She was diagnosed with FAP and colorectal adenocarcinoma and underwent total proctocolectomy with end ileostomy. She subsequently underwent a total thyroidectomy which revealed CMV Papillary Thyroid Carcinoma (CMV-PTC). Since FAP can have diverse presentations, a high index of suspicion is needed in order to make an earlier diagnosis to reduce potential morbidity and mortality. Papillary thyroid carcinoma can predate colonic polyposis. Identifying CMV-PTC early on can serve as an opportunity diagnose FAP early.

A 61-year-old woman presented with a 2-month history of non-painful left eye proptosis. Imaging studies showed a superotemporal mass in the left orbit with intracranial extension. Surgical excision of the orbitocranial mass was performed and histopathologic examination revealed metastatic papillary thyroid carcinoma. She subsequently underwent total thyroidectomy. Orbital metastasis from thyroid carcinoma is rare and can be the initial manifestation of occult disease in 63% of cases.

We report a case of an uncommonly aggressive presentation of the rare entity of synchronous papillary (PTC) and follicular thyroid carcinomas (FTC) in a 67-year-old woman initially presenting with thyrotoxicosis from Graves’ disease. She was found to have two thyroid nodules with extensive intra-cardiac tumour thrombus, symptomatic left pelvis bony metastasis with pathological fracture, pulmonary metastases and mediastinal lymph node metastases. Further investigations suggested a diagnosis of synchronous papillary and metastatic follicular thyroid cancer. Treatment with radical surgery followed by adjuvant therapeutic radioiodine ablation was proposed, but the patient declined all forms of cancer-specific therapy and was elected solely for a palliative approach to treatment. We discuss the diagnostic considerations in arriving at the diagnosis of synchronous thyroid malignancy – in this case the clear features of PTC and the strong probability of FTC due to invasiveness and metastatic follicular lesions. This case underscores potential limitations of the ACR TI-RADS system, notably with certain ultrasonographic features suggesting malignancy that might not be adequately captured. Notably, the aggressive presentation of DTC in this case may be contributed by the concurrent presence of Graves’ Disease, suggesting heightened vigilance when assessing potential thyroid malignancies in such patients.

Objective:To explore the safety and feasibility of bilateral axillo-breast approach （BABA） robot in the operation of thyroid cancer in obese women. Methods:The clinical data of 81 obese female patients who underwent da Vinci robotic thyroid cancer surgery（robotic group） at the Department of Thyroid and Breast Surgery, PLA 960 Hospital from May 2018 to December 2021 were retrospectively analyzed and compared with the clinical data of 106 obese female thyroid cancer patients who underwent open surgery（open group） during the same period. The age, body mass index（BMI）, mean time of surgery, mean postoperative drainage, tumor diameter, postoperative tumor stage, number of lymph node dissection in the central and lateral cervical regions, number of positive lymph nodes in the central and lateral cervical regions, postoperative cosmetic outcome satisfaction score, mean postoperative hospital stay and postoperative complications of all patients were counted. The results were analyzed using SPSS 26.0 statistical software, and the count data were compared using the χ² test, and the measurement data were compared using the t test. Results:All patients completed the operation successfully, and there was no conversion in the robot group, postoperative pathological results were all composed of papillary thyroid carcinoma. The operation time in the robot group was（144.62±36.38） min, which was longer than that in the open group（117.06±18.72） min（P<0.05）. The average age of the robot group was（40.25±9.27） years, which was lower than that of the open group（49.59±8.70） years（P<0.05）. The satisfactory score of cosmetic effect in the robot group（9.44±0.65） was higher than that in the open group（5.23±1.07）（P<0.05）. There was no significant difference in tumor diameter, BMI, average postoperative drainage, temporary hypoparathyroidism and recurrent laryngeal nerve injury, number of central and lateral cervical lymph node dissection, number of positive lymph nodes in the central and lateral cervical regions, and average postoperative hospital stay between the two groups. There was no permanent hypoparathyroidism and recurrent laryngeal nerve injury in both groups. Conclusion:The application of BABA pathway robot in thyroid cancer surgery in obese women is safe and feasible, and the cosmetic effect is better after operation.

Objective:To analyze the clinical significance of multigene assay in papillary thyroid carcinoma（PTC）. Methods:Patients who underwent thyroidectomy in a tertiary hospital from August 2021 to May 2022 were enrolled. The eight-gene panel was used to detect the tumor tissue of patients, and the correlation between gene mutations and clinical features was analyzed. Results:Among 161 patients, mutation rate of BRAF V600E, RET/PTC1 and TERT promotor were 82.0%, 6.8% and 4.3%, respectively. BRAF V600E mutation was more common in male patients（P=0.023）. TERT promotor-mutated tumors had a large diameter（P=0.019）, a high proportion of multifocal lesions（P=0.050）, and a large number of lymph node metastases（P=0.031）. Among 89 patients who completed preoperative BRAF detection, there was a strong consistency between the preoperative aspiration test and postoperative panel（Cohen κ=0.694, 95%CI: 0.482-0.906, P<0.01）. In the hematoxylin-eosin sections obtained from 80 patients, BRAF V600E was still the main type of gene mutation, and the classical/follicular type was more distributed. TERT promotor and RET/PTC1 mutation were the main genetic events for tall-cell/columnar/hobnail type and diffuse sclerosing type, respectively. One-way ANOVA showed that there were differences in diagnosis age（P=0.029） and tumor size（P<0.01） among different pathological types. Conclusion:As a simple and feasible clinical detection method for PTC, the multigene assay can supplement the identification of important genetic events other than BRAF V600E, and provide more prognostic information and follow-up hints for postoperative patients.

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.

A 23-year-old woman underwent left thyroid lobectomy and isthmusectomy for a 2 cm diameter firm mass on the left side of the neck that was also visualized on ultrasonography. The specimen consisted of a 22-gram thyroid gland composed of the left lobe, isthmus and a pyramidal lobe. Cut section of the left lobe showed a 3.5 cm diameter solitary, discrete and encapsulated mass with a tan lobulated and solid cut surface. The rest of the thyroid tissues had red-brown meaty cut surfaces. Microscopic section shows a follicular-patterned proliferation enclosed by a thin fibrous capsule with frequent Sanderson polster-like papillary excrescences. (Figures 1 and 2) Both the follicular and the papillary structures are lined by cuboidal to columnar follicular epithelial cells that had ample eosinophilic to pale cytoplasm and uniformly sized, minimally enlarged, generally round, and monolayered nuclei without nuclear grooving, folds, pseudoinclusions, and chromatin clearing. There are no mitotic figures seen. Some of the papillary structures have delicate vascular cores. (Figure 3) There are no psammoma bodies noted. The follicles contain variable amounts of pale eosinophilic colloid ranging from colloid-poor crowded follicles to those with ample colloid that have frequent peripheral scalloping. (Figure 4) Exhaustive sections failed to disclose capsular or vascular invasion. Based on the microscopic features, a diagnosis of follicular adenoma with papillary architecture was rendered.
