Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

A nearly painless ulcer usually found on the leg, characterized by an indurated, elevated edge and a nongranulating base.
See also: ulcer
causing little pain; slow growing.
a local defect, or excavation of the surface of an organ or tissue, produced by sloughing of necrotic inflammatory tissue. They occur in all organs and tissues and are to be found under those headings, e.g. abomasal, corneal, gastric.

see set-fast (2).
a rapidly expanding, erosive ('melting') corneal ulcer, seen particularly in brachycephalic breeds of dogs.
acute ulceration of the stomach or duodenum seen after severe burns of the body in humans.
see decubitus ulcer.
linear, branching pattern of ulceration on the cornea; characteristic of herpesvirus infections. See also herpetic keratitis.
a large, superficial, irregularly shaped corneal ulcer, typically formed by the coalescence of several dendritic ulcers.

infectious dermal ulcer
a systemic, fatal bacteremia of snakes manifested by multiple, small cutaneous ulcers. Called also scale rot.
is rare in all species. When they do occur, intestinal ulcers usually cause signs of chronic enteritis. It is a common lesion in adenocarcinoma of the intestine. See also peptic ulcer.

see collagenase ulcer (above).
a gastric ulcer viewed tangentially radiographically creates a mound in the otherwise smooth outline of radiopaque material in the stomach.
necrotic ulcer of swine
see ulcerative granuloma of swine.
one that involves the entire thickness of an organ, creating an opening on both surfaces. See also ulcer perforation.
a necrotizing lesion in which tissue destruction is prominent.
a chronic, superficial corneal ulceration in dogs, particularly common in Boxers, that extends into the superficial stroma, often undermining epithelium at the edges. The cause is unknown but abnormalities of the basal epithelial cells and anterior stroma have been noted. Response to the usual methods of treatment for corneal ulceration is characteristically very slow; superficial keratectomy is the treatment of choice. Called also superficial corneal erosion syndrome, Boxer ulcer.
superficial ulcerations or erosions of mucosa in the stomach, duodenum or colon. The possible predisposing factors include changes in the microcirculation of the gastric mucosa, increased permeability of the gastric mucosa barrier to H+, and impaired cell proliferation.
a corneal ulcer involving the stroma.
one due to imperfect nutrition of the part. In dogs, may develop in digital and metatarsal pads in association with tibial nerve injury.
