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

Alveolar soft part sarcoma (ASPS) of the uterine cervix is a rare malignancy, and 21 cases have been reported the literature from every language (including our case). Herein, we describe a 17-yearold female patient who presented with active vaginal bleeding. Pelvic examination revealed a 1.6 ×1.0×0.5-cm-sized soft mass protruding from the uterine cervix. The final pathological diagnosis was ASPS of the uterine cervix. Immunohistochemically, tumor cells were strongly nuclear positive for transcription factor E3. The patient remained disease free for 24 months without adjuvant therapy. The prognosis of ASPS in the cervix is considerably better than that of ASPS in soft tissues due to early clinical detection, small size, and resectability. ASPS should be considered in the differential diagnosis of an unusual epithelioid neoplasm showing organoid appearance with mild cytologic atypia and no/rare mitotic figures, particularly in young women. Pathologists should be aware of those unusual locations where ASPS may originate.

Abstract PDF

Background

The aims of this study were to evaluate the abilities of direct sequencing (DS), peptide nucleic acid (PNA) clamping, and pyrosequencing methods to detect epidermal growth factor receptor (EGFR) mutations in formalin-fixed paraffin-embedded (FFPE) non-small cell lung carcinoma (NSCLC) samples and to correlate EGFR mutational status as determined by each method with the clinical response to EGFR tyrosine kinase inhibitors (TKIs).

Methods

Sixty-one NSCLC patients treated with EGFR TKIs were identified to investigate somatic mutations in the EGFR gene (exons 18-21).

Results

Mutations in the EGFR gene were detected in 38 of the 61 patients (62%) by DS, 35 (57%) by PNA clamping and 37 (61%) by pyrosequencing. A total of 44 mutations (72%) were found by at least one of the three methods, and the concordances among the results were relatively high (82-85%; kappa coefficient, 0.713 to 0.736). There were 15 discordant cases (25%) among the three different methods.

Conclusions

All three EGFR mutation tests had good concordance rates (over 82%) for FFPE samples. These results suggest that if the DNA quality and enrichment of tumor cells are assured, then DS, PNA clamping, and pyrosequencing are appropriate methods for the detection of EGFR mutations.

Abstract PDF

BACKGROUND
Alterations in the phosphatase and tensin homolog (PTEN) are correlated with tumor progression. Downregulation of PTEN is related to drug resistance of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors in non-small cell lung cancer (NSCLC). The aim of this study was to evaluate the prognostic significance of PTEN in patients with NSCLC and its correlation with EGFR.
METHODS
Two hundred eighty eight surgically resected NSCLC samples, including 168 adenocarcinomas (ADCs), 99 squamous cell carcinomas (SCCs) and 21 other NSCLCs were analyzed for the PTEN. The results were correlated with other clinicopathological variables including EGFR amplification and mutation.
RESULTS
Loss of PTEN was detected in 42.4% of NSCLCs, specifically 28.6% of ADCs, 66.7% of SCCs, and 38.1% of others. Loss of PTEN was significantly associated with SCC, smoking, male gender, and higher stage. In a multivariate analysis, loss of PTEN was significantly associated with short progression-free survival (p=0.037). No association between PTEN and EGFR was observed.
CONCLUSIONS
These results suggest that loss of PTEN results in shorter progression-free survival in patients with NSCLC, and loss of PTEN is more associated with SCC, smoking, male gender, and higher T stage by the 7th tumor, node and metastasis staging system but not EGFR status.

Abstract PDF: BACKGROUND
CD44 is a cell surface receptor that has been implicated in tumor cell invasion and metastasis in a range of tumors of various organs, including breast, ovary, colon, lung, and brain. CD44 stimulates the invasive ability by interacting with matrix metalloproteinase 14 (MMP14). The expression of MMP14 on the cell surface is thought to trigger multiple proteinase cascades and to stimulate cell migration.
METHODS
A total 54 astrocytoma patients were eligible for this study. We performed a retrospective clinicopathological review and CD44 and MMP14 immunohistochemistry.
RESULTS
The expressions of CD44 and MMP14 were significantly correlated with the World Health Organization (WHO) grade. On univariate analysis, the WHO grade and the expression of CD44 were the significant prognostic factors affecting overall survival (OS) and disease progression free survival (DPFS). On the multivariate analysis by the Cox regression model, the only WHO grade was shown to be a significant independent prognostic factor for predicting the DPFS and OS.
CONCLUSIONS
In this study, the CD44 and MMP14 expressions were related to the WHO grade of astrocytoma. The CD44 expression status was a prognostic factor for DPFS and OS on univariate analysis, but it was not an independent prognostic factor on the multivariate analysis.

BACKGROUND
Increased glucose uptake, a process that is mediated by glucose transporter (Glut1) proteins, is an important metabolic feature in a variety of cancer cells. The overexpression of Glut1 in human cancers is known to be related to a variety of histopathological parameters, including histological grade, proliferation rate, and lymphatic invasion. The principal objective of this study was to evaluate Glut1 expression in the spectrum of pulmonary neuroendocrine (NE) tumors including typical carcinoid tumor (TC), atypical carcinoid tumor (AC), large cell neuroendocrine carcinoma (LCNEC), and small cell carcinoma (SCC), and to characterize the relationship between Glut1 expression and the histologic grade of NE tumors.
METHODS
19 TC, 7 AC, 13 LCNEC, and 6 SCC patients were included in this study. The percentages of Glut1-positive tumor cells in these patients were determined. For statistical analysis, Glut1 expression was subdivided into a Glut1-low expression group (0-30%) and a Glut1-high expression group (31-90%).
RESULTS
In our subgroup analyses, the histological grade of pulmonary neuroendocrine (NE) tumors was significantly correlated with Glut1 expression; TC (n=19, 3.6+/-4.2%), AC (n=7, 20.0+/-4.9%), LCNEC (n=13, 60.0+/-21.1%), and SCC (n=6, 74.2+/-16.9%). Glut1-high expression was significantly associated with high-grade NE tumors such as LCNEC and SCC (n=19, 62.6+/-21.0%) (p=0.000).
CONCLUSIONS
The results of this study appear to indicate that Glut1 overexpression is a consistent feature of high-grade NE lung tumors.

Abstract: Mineralizing pulmonary elastosis is a result of chronic alveolar hemorrhage forming iron encrustation of a pulmonary elastic tissue. It has been reported as a complication of some diseases such as bronchiectasis, idiopathic pulmonary hemosiderosis, and cardiac failure. It is extremely rare to occur with a giant cell carcinoma as we experienced. A 59 year-old man visited our hospital for cough and blood tinged sputum. A chest CT scan revealed 10 9 6 cm sized round mass in the left upper lobe. He had lobectomy of left upper lobe, but died of respiratory failure at the postoperative eighteenth day. The lung showed a necrotic tumor and a yellow tan consolidation around the mass. Microscopically, the tumor was composed of nests or syncytia of large bizarre cells and tumor giant cells, and was diagnosed as a giant cell carcinoma. Interestingly, in the surrounding lung parenchyma there were a lot of foreign body type giant cells phagocytizing iron encrustated elastic fibers, which were easily identified by elastic van Gieson and prussian blue stains. Those degenerated elastic fibers appeared in pulmonary interstitial tissue as well as blood vessel walls. The authors concluded tumoral hemorrhage and necrosis resulted in mineralizing pulmonary elastosis.
