Stomach, Glandular Stomach - Metaplasia, Squamous

comment:
Squamous metaplasia of the glandular stomach is characterized by a reversible change in which cuboidal or columnar mucosal epithelial cells are replaced by squamous epithelial cells ( Figure 1



recommendation:
Whenever present, squamous metaplasia should be diagnosed and graded based on the number and size of metaplastic areas. Associated lesions, such as inflammation, should be diagnosed separately.references:
