Abstract The diffuse sclerosing variant papillary thyroid carcinoma (DSPTC) is an uncommon form of this neoplasm. Some studies describe its high propensity for tumor invasion, metastasis, and mortality compared with classic papillary thyroid carcinoma. Histologic features of DSPTC may resemble diffuse inflammation as seen with Grave’s or Hashimoto’s thyroiditis, which makes initial diagnosis challenging. A 27-year-old female with Noonan’s Syndrome was evaluated on an outpatient basis after developing atrial fibrillation de novo. Thyroid function tests were consistent with hyperthyroidism with TSH: <0.005 (n: 0.300-3.000 uIU/mL), FT4: 3.59 (0.71-1.85 ng/mL) and FT3: 16.77 (n: 2.0-7.0 pmol/L). Diffuse goiter was noted on physical exam, but no ophthalmopathy or dermopathy was present. TRAB and TSI were elevated at 38.4 (n: <16%) and 423% (n: <140%) respectively. A twenty-four-hour radioiodine uptake was 48% (n:10-35%) and described as essentially homogenous with two foci of decreased radiotracer concentration suggestive of cold nodules. Thyroid ultrasound showed diffuse nodularity bilaterally with associated clusters of calcifications and no discrete nodules. No abnormal appearing lymph nodes were identified. Fine-needle aspiration of both nodular areas was positive for DSPTC. Total thyroidectomy with central neck dissection was performed. Gross and microscopic post-surgical pathology confirmed the presence of diffuse sclerosing papillary thyroid cancer, along with local metastasis to one central lymph node. Patient was scheduled for radioactive iodine therapy. Diffuse sclerosing variant is considered an aggressive histotype of papillary thyroid cancer. Ultrasound features include diffuse scattered microcalcifications with or without discrete nodules that may be confused with chronic inflammatory changes. Despite the limited number of cases, DSPTC is recognized to have specific characteristics, a high female to male ratio, and a young patient age. DSPTC has a high potential for aggressive biologic behavior if not treated promptly at the time of diagnosis. When suspected, total thyroidectomy with lymph node excision followed by radioiodine therapy has been proposed as the correct management to decrease the risk of persistent or recurrent disease.

Abstract Diffuse sclerosing variant (DSV) is a rare subtype of papillary thyroid cancer (PTC). Whether it represents a higher grade subtype than conventional PTC is not quite clear. Furthermore, there are limited data on its long-term outcome and its molecular genetics. In this report, we studied all cases of DSV PTC seen at our center during the last 20 years. Out of more than 6000 patients (pts) with differentiated thyroid cancer, only 37 were DSV. We reviewed the clinical and histopathological features, management and outcome of these cases. In addition, molecular genetics is partially achieved; 17 out of these 37 cases have been genotyped for BRAFV600E, TERT promotor mutations, NRAS, HRAS and KRAS mutations. The molecular profiling of the other 20 cases is being done. A total of 37 pts were studied {(12 Males:25 Females, median age 21 years (8-89)}. One pt had lobectomy and the other 36 pts (97.3%) had a total thyroidectomy. Central only (4 pts) or central/lateral lymph node dissection (29 pts) were performed. The median tumor size was 4.5 cm (1.5-8.1). The tumor was multifocal in 27 cases (73%), with extrathyroidal invasion in 27 (73%) and lymphovascular invasion in 24 pts (64.8%). A background lymphocytic thyroiditis was present in 12 pts (32.4%). Lymph node metastases were present in 34 pts (92%) and distant metastases in 13 pts (35%). The sites of metastasis are lungs in 12 pts (32.4%) and lungs and bone in 1 pt. Twenty pts (54.1%) were in TNM8 stage 1, 10 pts (27%) in stage 2, 1 (2.7%) in stage 4a, 3 (8.1%) in stage 4b and 3 unstageable. The ATA risk classification for these pts was 4 pts (10.8%) in low, 12 (32.4%) in intermediate, 19 (51.4%) in high-risk groups and 2 could not be assessed. I-131 was administered to 33 pts (89.2%). The median administered activity was 136 mCi (46-218). Fifteen pts (40.5%) received additional therapies (3 surgeries, 7 RAI, 5 surgeries, and RAI). In 17 pts (46%) which were genotyped, only 3 tumors (8.1%) had BRAFV600E mutation, 1 (2.7%) had TERT promotor C228T mutation and none had RAS mutations. At the last follow up, 15 pts (40.5%) achieved an excellent response, 9 (24%) an indeterminate response, 6 (16.2%) with a structural disease, and 7 (19%) were lost for follow up. Conclusion: DSV PTC is a rare variant, occurs mostly in adolescent and young pts, characterized by aggressive histopathological features and high rates of lymph node and distant metastases but the commonly reported mutations in PTC are rare in DSV and mortality is absent.

We present a case of Warthin-like papillary thyroid carcinoma in a 22-year-old woman and a review of the literature on the topic. The patient had the occasional discovery of a hypoechoic thyroid nodule of approximately 18 mm, characterized by irregular margins, hyperechoic spots, rich intra- and perilesional vascularization, and a suspicious enlarged right laterocervical lymph node. Fine-needle aspiration was performed for both lesions and the diagnosis of papillary thyroid carcinoma without lymph node involvement was made. The patient underwent thyroidectomy and central neck lymphadenectomy without complications. Histopathological examination suggested a Warthin-like papillary carcinoma of the thyroid gland, with all the removed lymph nodes being free of disease. The patient subsequently underwent iodine ablative therapy and she remains free of disease one year after surgery. Warthin-like papillary thyroid carcinoma is a recently described variant of papillary thyroid cancer that is frequently associated with lymphocytic thyroiditis. Morphologically, it resembles Warthin tumors of the salivary glands, with T and B lymphocytes infiltrating the stalks of papillae lined with oncocytic cells. Surgical and postoperative management is identical to that of classic differentiated thyroid cancer, while prognosis seems to be favourable.

Objective To determine the relationship between age and rate of lymph node metastasis, nodal burden of disease, as well as rate of lateral neck disease in papillary thyroid cancer, especially in patients aged <30 years. Study Design Population-based cross-sectional study. Setting Population-based cancer database. Methods Data were extracted from the SEER 18 database (Surveillance, Epidemiology, and End Results) of the National Cancer Institute. The study cohort included 59,330 patients diagnosed with papillary thyroid cancer between 1988 and 2015. Patients aged 0 to 10 years, 11 to 20 years, and 21 to 30 years old were compared with those >30 years. All analyses were adjusted for sex, race, and T classification. Results The overall rate of lymph node metastasis was 26.11%, which increased with decreasing age. Adjusted odds ratios of lymph node metastasis were 7.19 (95% CI, 3.76-13.75) for the 0- to 10-year-old group, 3.45 (95% CI, 3.08-3.87) for the 11- to 20-year-old group, and 2.28 (95% CI, 2.15-2.41) for the 21- to 30-year-old group, relative to the group >30 years old. Decreased age was also associated with increased total positive nodes, increased lymph node ratio, and increased risk of lateral neck disease. Conclusion Pediatric and early young adult patients with papillary thyroid carcinoma have a greater risk of lymph node metastasis, greater burden of nodal disease, and a greater risk of lateral neck metastases.

Background: Although lymph-node metastases are common in papillary thyroid cancer, there is considerable debate concerning the use of routine prophylactic lymph-node group VI dissection for all patients undergoing total thyroidectomy. This study was identification the complications and the rate of recurrence of total thyroidectomy plus lymph node group VI dissection in papillary thyroid carcinoma patients. Materials and methods: A prospective study was conducted on 60 patients with papillary thyroid carcinoma. They underwent total thyroidectomy with or without lymph node group VI dissection. Evaluation of postoperative complications and early recurrence rate /distant metastasis after 2 years. Results: The incident of transient hypoparathyroidism in the grouptotal thyroidectomy with or without lymph node group VI dissection respectively 13.3% and 6.7%. Neck lymph node dissection group VI helps detect 40.9% of cases of metastatic lymph nodes clinically undetectable. Neck lymph node recurrence rate in patients with lymph node group VI dissection is lower than group without dissection (3.3% versus 23.3%). Conclusions: Lymph nodes group VIdissection in preventive treatment of papillary thyroid carcinoma should be done. Key words: PTC, lymph-node group VI dissection

Papillary thyroid carcinoma frequently metastasizes to regional lymph nodes. However, cervical lymph node metastasis as a sole manifestation of occult papillary thyroid carcinoma is rarely observed. Ectopic thyroid is an uncommon condition defined as the presence of thyroid tissue at a site other than pretracheal area. Approximately 1–3% of all ectopic thyroid tissue is located in the lateral neck. This entity may represent the only functional thyroid tissue in the body. Malignant transformation of ectopic thyroid is uncommon; but even rarer is the development of papillary carcinoma on it. We present a case of a 33-year-old man with an incidental lateral neck mass diagnosed after a motor vehicle accident. Total thyroidectomy and lymph node resection were completed without evidence of papillary thyroid carcinoma. Malignant transformation of heterotopic thyroid tissue was the final diagnosis. The possibility of an ectopic thyroid cancer should be considered in the differential diagnosis of a pathological mass in the neck. The uniqueness of this case strives in the rarity that the thyroid gland was free of malignancy, despite ectopic tissue being positive for thyroid carcinoma. Management strategies, including performance of total thyroidectomy, neck dissection, and treatment with radioiodine, should be based on individualized risk assessment.

ABSTRACT Autoimmune rheumatic diseases, such as polymyositis and dermatomyositis, have been demonstrated to carry a risk of the development of malignancy. Thyroid cancer is a rare occurrence in this setting; however, multiple cases have been reported. We present two cases of papillary thyroid carcinoma associated with dermatomyositis and polymyositis. The first patient is a 64-year-old female found to have papillary thyroid cancer after the diagnosis of polymyositis who underwent thyroid resection. The second patient is a 51-year-old male who was found to have synchronous papillary thyroid cancer and small cell carcinoma of the lung. He did not undergo thyroid resection due to widely metastatic lung cancer. We describe two cases of papillary thyroid cancer associated with autoimmune rheumatic disease. Though it is rare, thyroid cancer should remain in the differential diagnosis of a patient with new onset autoimmune rheumatic disease, as this may alter the eventual management of these patients.
