Testicular carcinoid tumors are very rare, accounting for less than 1% of all testicular tumors. We report a rare case of a testicular carcinoid tumor with extensive lymphatic invasion. A 42-year-old man presented with a painless, enlarged right testicular mass. There was no history of injury or discomfort in this region. Right radical orchiectomy was performed, which showed a well-defined, non-encapsulated solid white mass with calcification (7.0 × 4.5 × 3.5 cm) and absence of cystic components. Microscopic examination using hematoxylin and eosin staining of the tumor sections identified organoid, trabecular, and solid patterns with rosette formation. Extensive multifocal lymphatic invasion was observed. Immunohistochemistry was positive for synaptophysin, chromogranin, and CD56. Testicular carcinoid tumors usually show good prognoses; however, there was extensive lymphovascular invasion in this case. Thus, in the case of unusual presentation of the disease, close follow-up is necessary.

Background
Ovarian epithelial cancer (OEC) is the second-most common gynecologic malignancy. CD109 expression is elevated in human tumor cell lines and carcinomas. A previous study showed that CD109 expression is elevated in human tumor cell lines and CD109 plays a role in cancer progression. Therefore, this study aimed to determine whether CD109 is expressed in OEC and can be useful in predicting the prognosis.
Methods
Immunohistochemical staining for CD109 and reverse transcription-quantitative polymerase chain reaction was performed. Then we compared CD109 expression and chemoresistance, overall survival, and recurrence-free survival of OEC patients. Chemoresistance was evaluated by dividing into good-response group and poor-response group by the time to recurrence after chemotherapy.
Results
CD109 expression was associated with overall survival (p = .020), but not recurrence-free survival (p = .290). CD109 expression was not an independent risk factor for overall survival due to its reliability (hazard ratio, 1.58; p = .160; 95% confidence interval, 0.82 to 3.05), although we found that CD109 positivity was related to chemoresistance. The poor-response group showed higher rates of CD109 expression than the good-response group (93.8% vs 66.7%, p = .047). Also, the CD109 mRNA expression level was 2.88 times higher in the poor-response group as compared to the good-response group (p = .001).
Conclusions
Examining the CD109 expression in patients with OEC may be helpful in predicting survival and chemotherapeutic effect.

Abstract PDF

Myoepitheliomas are well-established to occur in the salivary glands, but they have also been described in the breast, upper aerodigestive tract, skin, and soft tissues. We report here on a unique case of primary myoepithelioma that occurred in the right testis of a 28-year-old man. The tumor was entirely confined to the testis and it was clearly separated from the epididymis. Histopathology revealed mixed architectural patterns in which the reticular areas merged into the chondromyxoid stroma. The tumor cells, which were focally immunoreactive to pancytokeratin and S-100 protein, were round to ovoid and spindly arranged in cords, strands, and fascicles. They showed mild nuclear pleomorphism, sparse mitotic figures and a low Ki-67 proliferative index. There was no ductal differentiation in the tumor. To the best of our knowledge, there has been only one case report of a primary testicular myoepithelioma in the English medical literature.

Abstract PDF

BACKGROUND
The epithelial mesenchymal transition (EMT) is intimately associated with tumor hypoxia. The present study was conducted to investigate the immunohistochemical relationship between hypoxic and EMT-related molecules in non-small cell lung carcinoma (NSCLC).
METHODS
Immunohistochemical staining for hypoxia inducible factor (HIF)-1alpha, carbonic anhydrase (CA) IX, TWIST, and E-cadherin proteins was performed in 146 cases of NSCLC (80 cases of adenocarcinoma and 66 cases of squamous cell carcinoma) using tissue microarray blocks.
RESULTS
HIF-1alpha, TWIST, CA IX, and E-cadherin were expressed in 58 (40%), 90 (62%), 82 (56%), and 36 (25%) of 146 NSCLC cases, respectively. TWIST expression was positively correlated with HIF-1alpha expression (p = 0.03) and inversely correlated with E-cadherin expression (p < 0.01). TWIST and CA IX expression were not significantly interrelated, but each showed a relationship with histological tumor grade. However, the expression of these molecules had no significant effect on clinical staging or patient survival.
CONCLUSIONS
Although TWIST expression was correlated positively with HIF-1alpha expression and inversely correlated with E-cadherin, HIF-1alpha expression was not associated with E-cadherin expression. However, considering the relationship between HIF-1alpha and TWIST expression, further studies should be performed to demonstrate the role of hypoxia-induced EMT in NSCLC.
