The incidence of heterotopic gastric mucosa located in the submucosa in resected stomach specimens has been reported to be 3.0 to 20.1%. Heterotopic gastric mucosa is thought to be a benign disease, which rarely becomes malignant. Heterotopic gastric mucosa exists in the gastric submucosa, and gastric cancer rarely occurs in heterotopic gastric mucosa. Since tumors are located in the normal submucosa, they appear as submucosal tumors during endoscopy, and are diagnosed through endoscopic biopsies with some difficulty. For such reasons, heterotopic gastric mucosa is mistaken as gastric submucosal tumor. Recently, two cases of early gastric cancer arising from heterotopic gastric mucosa in the gastric submucosa were treated. Both cases were diagnosed as submucosal tumors based on upper gastrointestinal endoscopy, endoscopic ultrasound, and computed tomography findings, and in both cases, laparoscopic wedge resections were performed, the surgical findings of which also suggested submucosal tumors. However, pathologic assessment of the surgical specimens led to the diagnosis of well-differentiated intramucosal adenocarcinoma arising from heterotopic gastric mucosa in the gastric submucosa.

To evaluate the effect of alteration of left atrial pressure. volume and wall tension on the circulating plasma level of atrial natriuretic peptide(ANP), 15 patients with left atrial hypertension due to mitral stenosis were studied at the time of percutaneous balloon mitral valvuloplasty(PMV). Hemodynamic measurements and plasma atrial natriuretic peptde levels were obtained before, immediately(5-10min) after and 24h after valvuloplasty, and echocardiographic left atrial size, wall tension and mitral valve area were measured bdfore and 24h after valvuloplasty. 1) Immediately after valvuloplasty, left atrial pressure, pulmonary atrial pressure and mean diastolic pressure gradient across the mitral valve decreased, and the mitral valve area by Gorlin's method increased, significantly. Plasma atrial natriuretic peptide level(atright and left atrium, pulmonary artery and aorta) rose significantly after balloon inflation. This rising may reflect a transient increase in left atrial pressure and volume expansion associated with mitral valve occlusion by balloon. 2) Twenty four after valvuloplasty, mitral valve area increased, and left atrial volume and wall tension decreased, significantly. Plasma atrial natriuretic peptide level(at right atrium, pulmonary artery and aorta) fell significantly, too. In conclusion, change of plasma atrial natriuretic peptide le.vel before and after percutaneous balloon mitral valvuloplasty reflect hemodynamic alteration of right and left atrium.

Small cell carcinoma (SmCC) of stomach is a very rare and aggressive malignancy with extremely poor prognosis. Most patients with gastric SmCC die within 1 year of diagnosis. A standard treatment for gastric SmCC has not been established, but surgical excision and/or combination chemotherapy should be considered to promote long term survival. We report a case of small cell carcinoma of stomach in a 66-year-old woman with dysphagia. A gastroscopic examination revealed a polypoid mass with ulceration on the lesser curvature of the gastric body extending to the gastro-esophageal junction. An endoscopic biopsy showed a solid proliferation of small, monotonous tumor cells with hyperchromatic nuclei and scanty cytoplasm. Immunohistochemically, the neoplastic cells were positive for chromogranin, synaptophysin and NSE, and negative for CD45. No tumor was detected on examination of the chest. Therefore, primary SmCC was diagnosed preoperatively.

Most hamartomatous polyps in the stomach occur in patients with adenomatous polyposis coli and dysplasia. The authors report a case of a 57-year-old man without prior history of polyposis coli who presented with adenocarcinomas derived from hamartomatous polyps in the stomach. The patient underwent a radical subtotal gastrectomy with Billroth I anastomosis. Pathology revealed adenocarcinomas with moderate differentiation without evidence of lymph node metastasis in 60 nodes. We report a case of gastric cancers arising from de novo gastric hamartomatous polyps.

The cell surface molecule identified by a monoclonal antibody(TE-1) to human thymic epithelial cell showed the specificity for thymic epithelial cells of both the cortex and medulla. TE-1 reacted with the epithelial cells of normal thymus and thymoma in fresh frozen tissues. The antigen recognized by TE-1 was mostly confined to the cell surface membrane and arranged in reticular network with long processes between thymocytes. On immunohistochemical analysis, TE-1 did not recognize normal epithelial cells of the uterine cervix, skin and stomach, and neoplastic cells of squamous cell carcinoma and gastric adenocarcinoma, all of which were stained with anti-cytokeratin monoclonal antibody. Among the tumor cell lines tested with flow cytometry, most of epithelial and all of hematopoietic cell origin were not labeled with TE-1. In summary, TE-1 appears to be a monoclonal antibody against a surface antigen of human thymic epithelial cell that is immunohistologically different from known epithelial cell surface antigens reported so far.

Varicella is usually a benign childhood disease, while in the adult is an infrequent but potentially serious infection. Varicella pneumonia is a potentially life-threatening complication that should be suspected in any adult with chickenpox and respiratory symptoms. In the adult it may be complicated by pneumonia with high morbidity and mortality rates. We present a case of varicella pneumonia complicated the course of chickenpox in the living-related donor renal transplant recipient. A 30-year-old male received an allograft kidney from his father following treatment with cyclosporine and low-dose steroids. Allograft function was stable over the next 27 months. He was admitted hospital with a week history of generalized varicelliform rash, malaise, fever, chills and a cough. Three weeks ago, his nephew (7-year-old) had chickenpox who was living together in the same house. On examination he looked severely ill, febrile and his skin was covered with typical chickenpox eruption. Auscultatory examination was unremarkable while chest X-rays revealed bilateral interstitial infiltration. HRCT findings showed multiple variable sized nodules, patchy ground-glass opacities, and some consolidation in both lower lung. Treament with i.v. acyclovir was started and continued for 10 days. The patient response to the treatment was excellent with complete resolution of pneumonia.

Branch duct intraductal papillary mucinous neoplasms of the pancreas (BD-IPMN) without malignant features rarely developed into invasive cancer. However, invasive cancer is aggressive once an invasive change occurs. We report three cases of invasive cancers which developed in patients with BD-IPMN and they showed grave clinical courses. All patients were diagnosed with BD-IPMN < 3 cm without malignant features on imaging. Invasive cancer was detected at 2.5 years, 3.0 years, and 4.0 years after BD-IPMN detection in each patient. The intervals of invasive cancer and the last follow-up were 9 months, 3 years, and 1.5 years in the three patients, respectively. All patients were diagnosed with locally advanced pancreas invasive cancers and were treated with palliative chemotherapy or conservative management. The patients died at 3 months, 9 months, and 10 months after the diagnosis of invasive cancers, respectively. We report three cases of invasive cancer developed in BD-IPMN patients and followed fatal courses.
