Tongue - Ulcer
comment:Ulcers and erosions can occur anywhere in the gastrointestinal tract, including the tongue. An erosion involves the loss of superficial epithelium of the mucosa, whereas an ulcer ( Figure 1 and Figure 2 ) involves loss of the full thickness of epithelial cells and extends to the lamina propria. Ulceration and inflammation can be the result of spontaneous disease or local or systemic toxic injury. Ulcers on the tongue can be caused by malocclusion with incisor overgrowth or can be secondary to uremia. They are typically accompanied by inflammation and may also be accompanied by myocyte degeneration.
recommendation:Ulceration and erosion of the tongue should be diagnosed and graded. Edema, inflammation, and hyperplasia of the adjacent epithelium should not generally be diagnosed separately unless they are prominent components of the lesion. Necrosis of the epithelium is diagnosed instead of erosion or ulceration if the necrotic epithelium is still present and attached to the underlying lamina propria.
