The value of this database will be literally doubled only when it is givena search function. Classification of diseases is in accordance with theJapanese Classification of Colorectal and Gastric Carcinoma. Presentationsinclude malignant neoplasms, benign neoplasms and lesions similar toneoplasms. Examples of lesions attributable to inflammatory diseasesliable to be misdiagnosed as neoplasms can also be searched.

Pictorial images are divided into groups of x-ray images (monochrome),endoscopic images, resected specimen images (macro) and histpathologicimages (micro). The images may be searching according to specificobjectives.

When more than one image at a time is targeted for searching, these willbe presented first as thumbnails in lists of 20 at a time. If there aremore than 20 thumbnails, click the [next] button to scroll the next page.
