RESUMEN
Hyalinizing trabecular tumor (HTT) is a rare thyroid tumor with low to minimal malignant potential. HTT is often misinterpreted as other thyroid tumors, including papillary thyroid carcinoma (PTC) and medullary thyroid carcinoma (MTC), on fine-needle aspiration (FNA) cytology, because of its overlapping cytologic features, such as nuclear grooves and intranulcear pseudoinclusions. Although cytopathologists cannot definitely conclude HTT by FNA cytology, suspicion of HTT is necessary to avoid misdiagnosing HTT as PTC or MTC and to avoid unnecessary aggressive treatment. Here, we report a case of HTT with novel cytologic features in CellPrep liquid based cytology that was diagnosed as suspicious for papillary carcinoma by FNA and finally diagnosed as HTT in the surgical specimen.

PURPOSE: Breast cancer survivors have slightly increased the risk of second primary cancers. Breast, colon, uterine, and ovarian cancers are common secondary cancers in breast cancer survivors. In this study, we assessed the development of second primary cancers of breast cancer survivors in Korea. METHODS: Medical records of patients with breast cancer in 3 tertiary medical institutions were reviewed retrospectively. We evaluated secondary malignancy diagnosed at least 2 months after the breast cancer diagnosis. Based on the International Classification of Disease-9 codes of malignancies, secondary primary breast cancer records were evaluated with person-year adjustment. The standardized incidence ratio (SIR) was assessed using national cancer incidence. RESULTS: A total of 3,444 treatment records were included from 3 medical centers. The cumulative incidence of overall second primary cancers was 2.8% (n = 93). The SIR was significantly higher in all sites (1.56; 95% confidence interval [CI], 1.26–1.91), endometrial cancer (5.65; 95% CI, 2.06–12.31), biliary tract cancer (3.96; 95% CI, 1.19–8.60), and thyroid cancer (2.29; 95% CI, 1.67–3.08). CONCLUSION: The incidence of cancer was higher in breast cancer survivors compared to general population. Surveillance of secondary cancer in this group should be recommended individually considering the benefit related to the prognosis of primary breast cancer.

PURPOSE: Although laparoscopic appendectomy is a safe and effective procedure for the management of acute appendicitis, laparoscopic appendectomy in pregnancy has not been considered the preferred procedure until recently. The aim of this study was to evaluate the safety of laparoscopic appendectomy (LA) during pregnancy as compared with the control group that underwent open appendectomy (OA) during pregnancy. METHODS: The clinical data of all the patients who underwent appendectomy during pregnancy at our hospital between 2006 and 2009 was collected and retrospectively analyzed. Nineteen patients underwent LA and 11 patients underwent OA. The general features of the cases, the outcomes and the fetal status were evaluated. RESULTS: There were no significant differences in the length of the procedure, the hospital stay and the complication rate between the LA and OA groups. All the laparoscopic procedures were completed without conversion to an open operation. There were no significant differences between the two groups for premature delivery, the delivery type and the birth weight. There were no fetal losses or abortions. CONCLUSION: Our results demonstrate that LA was not inferior to OA in terms of the operative outcomes, the complication and both the fetal and maternal safety during 1st and 2nd trimesters of pregnancy. LA could be safely performed even in the 1st and 2nd trimesters of pregnancy using careful patient selection, safe operative techniques and the appropriate application of instruments.
