- Background
The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) has standardized the reporting of thyroid cytology specimens. The objective of the current study was to evaluate the nationwide usage of TBSRTC and assess the malignancy rates in each category of TBSRTC in Korea.
Methods Questionnaire surveys were used for data collection on the fine needle aspiration (FNA) of thyroid nodules at 74 institutes in 2012. The incidences and follow-up malignancy rates of each category diagnosed from January to December, 2011, in each institute were also collected and analyzed.
Results Sixty out of 74 institutes answering the surveys reported the results of thyroid FNA in accordance with TBSRTC. The average malignancy rates for resected cases in 15 institutes were as follows: nondiagnostic, 45.6%; benign, 16.5%; atypical of undetermined significance, 68.8%; suspicious for follicular neoplasm (SFN), 30.2%; suspicious for malignancy, 97.5%; malignancy, 99.7%.
Conclusions More than 80% of Korean institutes were using TBSRTC as of 2012. All malignancy rates other than the SFN and malignancy categories were higher than those reported by other countries. Therefore, the guidelines for treating patients with thyroid nodules in Korea should be revisited based on the malignancy rates reported in this study.

Abstract
PDF
Heterotopic gastric mucosa occurs in all areas of the gastrointestinal tract including the nasopharynx, tongue, esophagus, small intestine, colon, and rectum. Gastric heterotopia of the large bowel is infrequent, and most cases have been reported in the rectum. Review of the literature has revealed only eight cases involving the colon proximal to the rectum. Little is known of the natural history of gastric heterotopias, except that. It usually presents with gastrointestinal bleeding, though other serious complications such as bowel perforation, intussusceptions, and fistula formation, are possible. Further, it is unclear whether heterotopic gastric mucosa progresses to malignancy. Herein, we describe a case of adenocarcinoma of the transverse colon arising from gastric heterotopia. To the best of our knowledge, this is the first report of adenocarcinoma arising from heterotopic gastric mucosa in the colon.
