RATIONALE Gastrointestinal subepithelial tumors (SETs) with endoscopic features such as ulceration, a red color change, a peeled mucosal layer, and spontaneous bleeding could have malignant potential. However, we encountered a case of a lipoma that presented features different from the generally known features of gastrointestinal SETs. Therefore, we report an interesting rare case of a terminal...

Gastric mucosal microcirculatory disturbance in experimental animals is stressed as an important factor in the development of gastric ulceration induced by ethanol. In this study, we used a reflectance spectrophotometry system to investigate the effect of cetraxate on ethanol-induced gastric mucosal hemodynamics in anesthetized dogs. Forty percent ethanol caused a significant increase in the mu...

At bronchoscopic examination extensive areas of fibrinous slough covering bronchial mucosal inflammation and ulceration were seen in a case of progressive diffuse bronchopulmonary histoplasmosis. Rigid bronchoscopy was needed to obtain sufficient biopsy material for specific histological diagnosis.

The term Riga-Fede disease has been used to describe chronic traumatic ulceration that occurs on the ventral surface of the tongue by natal and neonatal teeth in infants. It is important to diagnose the lesion and treat it by eliminating the source of trauma. In this case report, the neonatal tooth was extracted and after 2 weeks the lesion was resolved and the baby was feeding well.In addition...

The purpose of this study was to examine the prognosis for patients with head and neck cancer after reirradiation using Cyberknife stereotactic body irradiation with special focus on mucosal ulceration. We conducted a retrospective multi-institutional review of 107 patients with previously irradiated head and neck cancer. The median follow-up time for all patients was 15 months, and the 2-year ...

Standard oesophageal scintigraphic techniques using 99mTc-colloids rarely identify oesophageal mucosal damage. Sucralfate can be labelled with 99mTc for the detection of oesophageal mucosal ulceration. This method uses two separate supine swallows of 10 MBq 99mTc-colloid in 10 ml, followed by a single supine swallow of 30 MBq 99mTc-sucralfate. The data are processed to give time-activity curves...

BACKGROUND In contrast with earlier reports that neutrophils play a primary part in non-steroidal anti-inflammatory drug (NSAID) injury to the stomach, recent evidence suggests only a secondary role for these cells. AIM To examine whether early microscopic changes induced by indomethacin in the gastric corpus of fasted rats and the antrum of fasted-refed rats involve neutrophil infiltration. ...

Objective. To raise awareness of plasma cell mucositis as a rare differential diagnosis for oral mucosal ulceration and its macroscopic similarity to malignancy. Method. We report a patient who presented with oral features suggestive of malignancy. A biopsy revealed plasma cell mucositis. Results. The patient successfully had a full excision of one lesion and a spontaneous resolution of the oth...

Mucus was sampled from the gastric mucosal surface of anaesthetised rats. Three weeks later these rats were orally dosed each day with aspirin (375 mg/kg) for six months. Then the number and size of the aspirin induced chronic gastric ulcers were assessed. Gel filtration chromatography of the mucus samples showed that mucus glycoprotein was present in both high and low molecular weight forms. T...

In the late 1990s the development of endoscopic submucosal dissection (ESD) using different knives revolutionized the spectrum of endoscopic resection techniques allowing en bloc resections regardless of the lesion’s size [5] . In combination with new data on the risk of lymph node metastases in early gastric cancer resection, criteria could be extended [6, 7] . The so-called expanded criteria ...
