Stomach, Forestomach - Hemorrhage in a female B6C3F1 mouse from a chronic study. Hemorrhage is present in the submucosa of the forestomach.

comment:Hemorrhage in the forestomach ( Figure 1 ) may be spontaneous (idiopathic), related to the gavage procedure, or due to direct/indirect chemical toxicity. It is often associated with inflammation.
recommendation:Hemorrhage should be diagnosed and graded based on the extent of the lesion. Hemorrhage that is a minor component of another process such as ulceration, necrosis, or inflammation is not diagnosed separately unless the hemorrhage is a prominent component of the lesion.
