A 63-year-old woman underwent thyroidectomy for papillary thyroid adenocarcinoma and cervical lymph node resection. Pathological analyses revealed the presence of signet cell carcinoma in a resected lymph node, which were apparently different from the pathological findings of thyroid carcinoma. No evidence of a primary tumor could be found elsewhere despite detailed examinations, including esop...

The appearance of a solitary lateral cervical cystic mass as the only initial presenting symptom of occult thyroid carcinoma is uncommon. Its presence is often misdiagnosed due to the more frequent branchial cyst in young people. Although oronasopharyngeal squamous cell carcinoma has been reported as the main cause of lymph neck node metastasis, thyroid papillary carcinoma may be responsible fo...

Thyroid squamous cell carcinoma is very rare. At present, it limited to case reports. Since the thyroid follicular epithelium non-squamous epithelium, how primary (SCC) of occurs still a controversial issue. Hashimoto’s thyroiditis (HT) considered be an independent risk factor for cancer, under basis HT, tumor cells evolve and develop papillary (PTC), particularly de-differentiate into SCC elus...

BACKGROUND We performed this retrospective study to identify predictors of right paraesophageal lymph node metastasis, and reviewed previous studies related to this topic. METHODS Between June 2005 and March 2015, 1107 patients were diagnosed with papillary thyroid carcinoma and underwent surgery at Pusan National University Hospital. RESULTS Right paraesophageal lymph node metastasis was o...

background: the presence of metastatic lymph nodes is the most important prognostic factor for gastric carcinoma; however, the optimal system for the accurate staging of lymph node metastasis for patients with gastric cancer remains controversial. this study was designed to compare five systems in relation to the n classification of gastric carcinoma. materials and methods: this multicentric hi...

OBJECTIVE Whether lymph-node dissection (LND) influences the lymph-node recurrence (LNR) risk in patients with papillary thyroid cancer remains controversial. The prognostic impact of macroscopic and microscopic lymph-node involvement at diagnosis is also an unresolved issue. A retrospective study was conducted to assess the influence of various LND procedures and to search for LNR risk factors...

BACKGROUND Papillary thyroid microcarcinoma (PTMC) describes a focus of papillary thyroid cancer that is less than 1 cm in size. These tumors are frequently found on histopathological examination of thyroid specimens, operated upon for an indication other than suspected malignancy. MATERIALS AND METHODS From 2005 to 2012, 94 of 1300 thyroidectomy specimens in our institution were found to hav...

Objective: To compare the clinical effect, safety, and cosmetic effect of lymph node dissection via endoscopic thyroidectomy open surgery in treatment papillary thyroid carcinoma (PTC).
 Methods: A retrospective analysis was performed on 86 patients with PTC admitted to Baoding No.1 Central Hospital from January 2020 December 2021. The enrolled were divided into (n = 34) 52) groups based d...

BACKGROUND Mixed medullary-follicular thyroid carcinoma denotes a rare and heterogeneous group of tumors displaying morphological and immunophenotypical features of both origins within the same lesion. METHOD We report a case of a 41-year-old woman with a lump in the right side of the neck, increasing in pain and size over several weeks. Serum levels of calcitonine (1140 ng/L) and carcinoembr...

OBJECTIVE The current work was conducted to study the disease status and treatment results of patients with differentiated thyroid carcinoma referred for radioactive iodine therapy. METHODS Retrospective review of 78 patients with differentiated thyroid carcinoma referred for radioiodine therapy in the Nuclear Medicine Unit, King Abdulaziz Hospital and Oncology Center, Jeddah, Kingdom of Saud...
