Esophageal metastasis from colorectal carcinoma is uncommon, and diagnosis of esophageal metastasis is difficult. We report a case of a 54-year-old woman with postoperative recurrence of rectal cancer metastasizing to the esophagus. She underwent rectectomy and adjuvant chemotherapy with fluorouracil, leucovorin plus oxaliplatin for stage IIIB rectal cancer. Three years later, she presented with dysphagia and cough. Computed tomography showed thickening of the esophagus wall, enlargement of the lymph nodes in the mediastinum and abdomen, and ground-glass opacities in the right lung...

BACKGROUND: Central lymph node (CLN) metastasis in papillary thyroid carcinoma (PTC) is common and being able to predict CLN metastasis helps surgeons determine individualized therapy. However, the relationship between contralateral CLN metastasis and the total number of positive lymph nodes (LNs) in the combined prelaryngeal and pretracheal region remains unclear. This study aimed to investigate whether the total number of positive LNs in the combined prelaryngeal and pretracheal region has clinical significance as a predictor for contralateral CLN metastasis...

BACKGROUND: Papillary thyroid carcinoma (PTC) generally has an indolent course, and non-operative management is acknowledged for papillary thyroid microcarcinoma (PTMC). However, some PTMCs progress and we cannot predict future progression at their presentation. BRAF and TERT promoter mutations were recently reported to be associated with poor outcomes of PTC. Here we sought to determine whether these mutations are associated with the progression of PTMCs, toward the goal of predicting progression/nonprogression...

BACKGROUND: Blood and lymph vessel invasion are well-recognized markers of tumor aggressiveness, as these are the routes that lead to metastases. Thyroid tumors, depending on the histological variant, tend to have distinctive biological behaviors and use different vascular routes to metastasize, yet the mechanisms underlying the metastatic process are still poorly understood. OBJECTIVES: The aim of this study was to assess how the lymph vessel density (LVD) in different histological types of thyroid tumors, and in their surrounding tissue, correlate with the presence of lymph node metastases (LNM) and tumor pathological features...
