gastric pit dysplasia

Thursday 23 February 2012

Despite wide acceptance of the chronic gastritis-intestinal metaplasia-dysplasia-carcinoma sequence, especially for intestinal-type gastric adenocarcinoma, the precise nature of the subtle precursor lesions of gastric cancer remains to be delineated.

For example, pit dysplasia with surface foveolar maturation is not well defined, nor is its prevalence and biological characteristics well characterized.

Gastric pit dysplasia is an important candidate precursor of gastric adenocarcinoma and may represent another morphologic step in the pathogenesis of gastric adenocarcinoma, especially of intestinal type.
