Gastric adenocarcinoma of fundic gland type is known to originate from the gastric mucosa of the fundic gland region without intestinal metaplasia. It is difficult to detect during endoscopy and diagnose histopathologically. The development of immunohistochemistry has enabled the diagnosis of gastric adenocarcinoma of fundic gland type by gastric phenotype. A 34-year-old man visited us for treatment of a 5 cm-sized low-grade dysplasia in the gastric fundus which was incidentally found during a health check-up endoscopy. Endoscopic submucosal dissection was performed successfully, and the final histopathology showed gastric adenocarcinoma of fundic gland type. Herein, we report a rare case of gastric adenocarcinoma of fundic gland type and its endoscopic and histopathologic findings.

BACKGROUND: Tumor hypoxia is associated with malignant progression and treatment resistance. Hypoxia-related factors, such as carbonic anhydrase IX (CA IX), glucose transporter-1 (GLUT-1), and vascular endothelial growth factor (VEGF) permit tumor cell adaptation to hypoxia. We attempted to elucidate the correlation of these markers with variable clinicopathological factors and overall prognosis. METHODS: Immunohistochemistry for CA IX, GLUT-1, and VEGF was performed on formalin-fixed, paraffin-embedded tissues from 125 cases of ovarian epithelial cancer (OEC). RESULTS: CA IX expression was significantly associated with an endometrioid and mucinous histology, nuclear grade, tumor necrosis, and mitosis. GLUT-1 expression was associated with tumor necrosis and mitosis. VEGF expression was correlated only with disease recurrence. Expression of each marker was not significant in terms of overall survival in OECs; however, there was a significant correlation between poor overall survival rate and high coexpression of these markers. CONCLUSIONS: The present study suggests that it is questionable whether CA IX, GLUT-1, or VEGF can be used alone as independent prognostic factors in OECs. Using at least two markers helps to predict patient outcomes in total OECs. Moreover, the inhibition of two target gene combinations might prove to be a novel anticancer therapy.

BACKGROUND: Epithelial-mesenchymal transition (EMT) is associated with tumor hypoxia. EMT is regulated, in part, by the action of TWIST, which inhibits of E-cadherin expression and may interfere with the p53 tumor-suppressor pathway. METHODS: We examined the expression of TWIST, E-cadherin, hypoxia-inducible factor 1alpha (HIF1alpha), and p53 by immunohistochemistry in 123 cases of ovarian epithelial cancers (OEC) to evaluate the role of TWIST in OEC. We assessed the association between protein expression and clinicopathologic parameters. RESULTS: The expression of TWIST, E-cadherin, HIF1alpha, and p53 proteins was found in 28.5%, 51.2%, 35.0%, and 29.3% of cases, respectively. TWIST expression was associated with higher histologic grade and unfavorable survival. TWIST expression was correlated with HIF1alpha expression and reduced E-cadherin expression. The altered HIF1alpha/TWIST/E-cadherin pathway was associated with lower overall survival (OS), while the co-expression of TWIST and p53 was correlated with lower progression-free survival. In the multivariate analyses, TWIST expression was an independent prognostic factor for OS. CONCLUSIONS: Our data imply that TWIST expression could be a useful predictor of unfavorable prognosis for OEC. TWIST may affect the p53 tumor-suppressor pathway. Moreover, hypoxia-mediated EMT, which involves the HIF1alpha/TWIST/E-cadherin pathway may play an important role in the progression of OEC.

Ectopic kidney is a rare congenital anomaly which occurs in approximately 1 in 1,000 live births. Intrathoracic kidney is the rarest type of the ectopic kidney, which constitutes < 5% of all ectopic kidney cases. It is often associated with congenital diaphragmatic hernia, which can cause severe respiratory distress. However, most patients with intrathoracic kidney are asymptomatic, and incidentally diagnosed with prenatal ultrasonography or chest radiography after birth as intrathoracic mass-like lesion. In this study, we report a case of an asymptomatic neonate with intrathoracic kidney. An intrathoracic mass was detected in plain chest radiography of a 17-day-old boy, and it was identified as the right kidney in the thoracic cavity by computed tomography and ultrasonography.Correction of the ectopic kidney and repair of diaphragmatic hernia were successful at the age of 52 days. After the operation, the right kidney was normally detected in the right renal fossa, and there was no recurrence of diaphragmatic hernia. To the best of our knowledge, the present case is the only reported case of intrathoracic kidney at the neonatal period, in South Korea. Careful review of chest radiography at the neonatal period and clinical suspicion of rare diseases like herniation of intraabdominal organ are needed.
