We present the first report of an immature teratoma arising from a germ cell testicular cancer invading the duodenum. While other seminomatous and non-seminomatous germ cell tumors are known to metastasize to the duodenum, this is the first such case involving an immature teratoma directly invading the duodenum from a metastatic retroperitoneal mass.

We report a case of squamous cell carcinoma of uterine cervix metastasizing to the duodenum through lymphatics. Para-aortic group of lymph nodes were involved which ultimately infiltrated the duodenum. On endoscopic examination, peri-ampullary growth was noted. Endoscopic biopsy from the growth was studied by routine histopathology and metastasis of squamous cell carcinoma involving duodenum wa...

At the end of the embryonic period of human development, c-kit immunoreactive (c-kit IR) cells identifiable as interstitial cells of Cajal (ICC) are present in the oesophagus and stomach wall. In the small and large bowel, c-kit-IR cells appear later (in the small bowel at 9 weeks, and in the colon at 10-12 weeks), also in the MP region. The object of this study was to determine the timing of a...

Basal HCO(3)(-) secretion across the duodenum has been shown in several species to principally involve the activity of apical membrane Cl(-)/HCO(3)(-) exchanger(s). To investigate the identity of relevant anion exchanger(s), experiments were performed using wild-type (WT) mice and mice with gene-targeted deletion of the following Cl(-)/HCO(3)(-) exchangers localized to the apical membrane of mu...

A 65-year-old woman presented with abdominal pain, weight loss, fatigue, and microcytic anemia. Esophagogastroduodenoscopy, until the second part of duodenum, was normal. Ultrasound and computed tomography demonstrated a solid mass in the distal duodenum. A repeat endoscopy confirmed an ulcerative, intraluminar mass in the third and fourth part of the duodenum. Segmental resection of the third ...

Tubulo-villous tumours of the duodenum are rare tumours which account for less than 1% of duodenal neoplasms, 88% of which are located in the second part of duodenum. The remaining 12% are equally distributed in first and third part of the duodenum [1, 2] . A high rate of malignant transformation complicates management with surgical treatment options ranging from wide local excision to radical ...

1. Two groups of four 18-month-old ewes fitted with a rumen cannula and re-entrant cannulas in the proximal duodenum were fed on one of two diets based on varying proportions of dried-grass meal, ground straw and barley. 2. The apparent availability, retention and amount of the mineral reaching the proximal duodenum were measured for calcium, phosphorus, magnesium, copper and zinc. Significant ...

dust colour and corrugated.in patches as if caused by bites. Duodenum of same colour. Whole length of intestines is of a somewhat similar colour with several small congested spots. In case No. 6 cancruiu oris. In case No. 7 most .oi the ai)chylostoma were found alive and adhering to duodenum and jejunum. In cases Nos. 8 aud 10 hemorrhagic spots in duodenum. In casesNos. 13 and 19 anchylostoma a...

The aim of the present study was to investigate the effect of systemic oxytocin (OT) and vasopressin (VP) on the motility of stomach and duodenum. Two plastic balloons made of condom were inserted into stomach and duodenum to monitor the change of mean pressure. Intravenous injection of OT (0.1-0.8 microg kg(-1)) or VP (0.02-0.08 IU kg(-1)) dose-dependently increased the stomach and duodenum pr...

CONTEXT Superior mesenteric artery syndrome is a life- threatening upper gastrointestinal disorder due to compression of duodenum as it poses a difficult diagnostic dilemma. Third part of duodenum is in fixed compartment bounded anteriorly by the root of mesentery and superior mesentery artery and posteriorly by the aorta and lumbar spine. On barium contrast study and abdominal computerized tom...
