A case of blue rubber bleb nevus syndrome with coronary artery fistula to left ventricle

SummaryA 69-year-old female was admitted to the hospital because of tarry stool and dyspnea on exertion. Multiple hemangiomas were noticed on the tongue, right arm and abdomen. Gastrointestinal examination revealed multiple polypoid lesions in the stomach and small intestine. In addition, coronary artery-left ventricular fistula formation and pulmonary arteriovenous malformation were shown by angiography. Compared with other reported cases of blue rubber bleb nevus syndrome, the present case was unique because of the coronary artery-left ventricular fistula, heart failure and the familiar incidence of heart failure.

Endoscopic studies on the minute structures of colonic mucosa in the follow-up observation of ulcerative colitis

SummaryThirty cases of ulcerative colitis were examined endoscopically by means of magnifying colonoscope with dye spraying method (the combined method), and their minute mucosal structures were classified into four categories endoscopically, which correlated well with the histological findings. By this procedure, it was easy to detect the subsidence of inflammation of the mucosa in the quiescent phase or to reveal the active inflammatory involvement of the bowel. Moreover, inspecting the minute changes of the colonie mucosa detected by the combined method, remission was more correctly decided and rigid control is contributing to the decrease in the recent rate of recurrence of ulcerative colitis.

A case of carcinoma of the ileocecal valve

SummaryA rare case of carcinoma of the ileocecal valve is reported, which is endoscopically confirmed by the colonofiberscope (Olympus CF-LB type apparatus) and a biopsy examination. The characteristic endoscopical findings of this tumor reveals an irregularly shaped tumor with superficial depression circumscribed at the ileocecal valve and the lack of peristalsis. Colonofiberscopy is of value in the differential diagnosis of the ileocecal lesions when carried out in the combination with roentgenographic studies and histological examination using biopsy specimens.
