Stomach, Forestomach - Erosion

comment:
An erosion ( Figure 1

recommendation:
Erosion of the forestomach should be diagnosed whenever present. Erosions should be graded based on the extent, number, and depth of the lesions. Secondary lesions, such as edema, inflammation, and hyperplasia of the adjacent epithelium, should not be diagnosed separately unless they are prominent components of the lesion or they are considered a primary lesion (e.g., the hyperplasia occurred prior to the erosion). Necrosis of the epithelium is diagnosed instead of erosion if the necrotic epithelium is still present and attached to the underlying lamina propria (see Stomach, Forestomach - Necrosis).related links:
