A glomus tumor in the mediastinum is very uncommon, and only five cases have been reported in the English literature. We recently encountered a 21-year-old woman with an asymptomatic mediastinal mass that measured 5.3 × 4.0 cm. Surgical excision was performed, and the tumor was finally diagnosed as mediastinal glomus tumor with an uncertain malignant potential. After reviewing this case and previous reports, we analyzed the clinicopathologic features associated with progression of such a tumor.

Abstract PDF

Thymic carcinomas are uncommon malignant tumors, and thymic adenocarcinomas are extremely rare. Here, we describe a case of primary thymic adenocarcinoma in a 59-year-old woman. Histological examination of the tumor revealed tubular morphology with expression of cytokeratin 20 and caudal-type homeobox 2 according to immunohistochemistry, suggesting enteric features. Extensive clinical and radiological studies excluded the possibility of an extrathymic primary tumor. A review of the literature revealed only two global cases of primary tubular adenocarcinomas of the thymus with enteric immunophenotype.

Abstract PDF

Background

Ezrin, a member of the ezrin-radixin-moesin family, is implicated in tumor progression, metastatic dissemination, and adverse outcomes, in several cancer types. In this study, we explored the clinicopathological significance of ezrin expression in non-small cell lung carcinomas (NSCLCs).

Methods

Immunohistochemical analysis of tissue microarray with 112 surgically resected NSCLC specimens, was performed to examine the ezrin expression. We also correlated ezrin expression with other clinicopathological features and prognosis.

Results

The ezrin-positive group revealed significantly higher correlation with pleural invasion (p=0.016) and pathologic stage (p=0.050). Univariate survival analysis showed that ezrin-positive group had a significantly shorter cancer-specific survival than ezrin-negative group (p=0.016). Meanwhile, female (p=0.030), no pleural invasion (p=0.023), no lymphatic invasion (p=0.026), and early pathologic stage (p=0.008) significantly correlated with longer survival. Multivariate survival analysis showed that variables such as ezrin positivity (p=0.032), female (p=0.035), and early pathologic stage (p=0.001) were independent prognostic factors for NSCLC.

Conclusions

Ezrin might be a molecular marker to predict poor prognosis of NSCLC.

Abstract PDF

Background

Papillary thyroid carcinoma (PTC) of the thyroid is the most common endocrine malignancy. High prevalence of an activating point mutation of BRAF gene, BRAF^V600E, has been reported in PTC. We assessed the efficiency of peptide nucleic acid clamp real-time polymerase chain reaction (PNAcqPCR) for the detection of BRAF^V600E mutation in PTC in comparison with direct sequencing (DS).

Methods

A total of 265 thyroid lesions including 200 PTCs, 5 follicular carcinomas, 60 benign lesions and 10 normal thyroid tissues were tested for BRAF^V600E mutation by PNAcqPCR and DS.

Results

The sensitivity and accuracy of the PNAcqPCR method were both higher than those of DS for the detection of the BRAF^V600E mutation. In clinical samples, 89% of PTCs harbored the BRAF^V600E mutation, whereas 5 follicular carcinomas, 50 benign lesions and 10 normal thyroid tissues lacked the mutation. The mutation was associated with aggressive clinical behaviors as extrathyroid invasion (p=0.015), lymph node metastasis (p=0.002) and multiple tumor numbers (p=0.016) with statistical significance.

Conclusions

The PNAcqPCR method is efficiently applicable for the detection of the BRAF^V600E mutation in PTCs in a clinical setting.
