leiomyoma of the esophagus is rare, but it is the commonest among the benigh tumors of the esophagus. among 95 cases of esophageal tumors, there was just 4 cases of leiomyoma (3 were females and 1 was male) and this is contrary to the reports already published. main symptoms of esophageal leiomyoma include: disphagia, pain and hematemesis from the above mentioned cases 1 tumor was in the thorac...

A solid pseudopapillary tumor of the pancreas (SPT) is alternatively called a 'Frantz tumor.' It was first named after its discoverer in year 1959. This has been previously designated as papillary epithelial neoplasm, low-grade and neoplasm pancreas. rare pancreatic neoplasm. typically affects young people female predilection. Its histogenesis rather debatable. Acinar, endocrine, ductal...

OBJECTIVE The pathophysiological data on Barrett's esophagus are scant in Asia, so the purpose of this study was to compare and analyze the pathophysiological characteristics of Barrett's esophagus and reflux esophagitis among Chinese in Taiwan. PATIENTS AND METHODS From November 2001 to January 2003, fifteen patients with Barrett's esophagus were consecutively enrolled as the Barrett's esoph...

Large iatrogenic gastrointestinal perforations (greater than 15–20mm) following therapeutic endoscopy remain a challenge despite growing expertise in endoscopic perforation closure techniques. Current treatment options include stenting [1,2] or clipping, including the use of an over-the-scope clipping device [3–5]. We present our experience using a combination of over-the-scope clipping and ste...

Pyloric gland adenoma is a rare neoplasm with a gastric epithelial differentiation. We report 23 cases of pyloric gland adenoma in older persons, with a mean age of 74 years (range 52 - 87 years). They occurred in the esophagus (3 cases), corporal gastric mucosa (7 cases), duodenum (10 cases), gallbladder (2 cases), and choledochus (one case). Histologically, they were characterized by closely ...

BACKGROUND The CDX2 (caudal-related homeobox gene 2) and PITX1 (pituitary homeobox 1) genes have essential roles in human development. Forced expression of Cdx2 alone in the murine stomach results in gastric intestinal metaplasia (IM). This study was undertaken to investigate the expression pattern of these critical morphogenesis genes in the Barrett's multistage carcinogenesis model. METHODS...

BACKGROUND Esophageal cancer (EC) is the eighth most common cancer worldwide. A worldwide-established consensus on therapeutic pathways for EC is still missing. Debate exists on whether neoadjuvant and adjuvant treatment regimens improve the prognosis and which surgical approach reaches objective benefits. SUMMARY This article discusses the appropriate option of the current different curative...

Histological development of digestive tract of the Caspian salmon, Salmo trutta caspius, from hatching to 6 month post-hatching was studied using light microscope. The digestive tract of newly hatched larvae was a simple, undifferentiated tube which continued from mouth to anus. In 10 days post hatching larvae, the alimentary canal became more differentiated and secretion was started activity, ...
