[Extracellular matrix in various forms of ulcerated stomach cancer, their differential diagnosis and morphogenesis]

Immunohistochemical study of the extracellular matrix in ulcerated stomach carcinoma has been performed. Material is taken from 70 patients having either ulcerated or non-ulcerated carcinoma, and from 10 patients with chronic stomach ulcer. Results of the study revealed additional criteria for a differential diagnosis of various forms of ulcerated stomach carcinoma and gave a description of their morphogenesis.
