Ulcer-loss of the epidermis, with adjacent epidermal hyperplasia and underlying inflammation arrow , in a male B6C3F1 mouse from a chronic study. Ulcer-loss of the epidermis, including the basement membrane arrow , in a male B6C3F1 mouse from a chronic study. Associated findings, such as inflammation, epidermal hyperplasia, hyperkeratosis, edema, or dermal fibrosis, should be described in the pathology narrative and not diagnosed separately unless, in the pathologist's judgment, a separate diagnosis is warranted.

Skin - Pustule. This post is intended to clear that up for you :. Quick Histo reminder : The esophageal mucosa consists of the surface keratinizing squamous epithelium, lamina propria, and muscularis mucosae. Beyond that is the submucosa, muscularis propria inner circular layer and outer longitudinal layer covered by the adventitial layer.

Characteristically erosions are accompanied by a rind of fibrin and inflammatory debris , allowing distinction of a true erosion from an artifactual epithelial denudation that occurs with aggressive tissue handling. This happens when the valve between the lower end of the esophagus and the stomach the lower esophageal sphincter does not close tightly.

This reflux can cause irritation, inflammation, or wearing away of the lining of the esophagus, which is called esophagitis. In severe cases, patches of the lining of the esophagus wear away completely, and ulcers may develop. Ulcers can be shallow or deep and can destroy the lining of the esophagus where they develop.

Treatment for ulcers in the esophagus usually means treating the GERD that caused the ulcer in the first place. Treatment for GERD involves lifestyle changes and medicine. Treatment sometimes involves surgery. The most common surgery to treat GERD is fundoplication surgery. During surgery, the upper curve of the stomach the fundus is wrapped around the esophagus and sewn into place so that the lower portion of the esophagus passes through a small tunnel of stomach muscle.

This surgery strengthens the lower esophageal sphincter, which stops acid from backing up into the esophagus as easily. This allows the esophagus to heal.
