See pyogenic granuloma.
a tumor-like mass or nodule of granulation tissue, with actively growing fibroblasts and capillary buds, consisting of a collection of modified macrophages resembling epithelial cells, surrounded by a rim of mononuclear cells, chiefly lymphocytes, and sometimes a center of giant multinucleate cells; it is due to a chronic inflammatory process associated with infectious disease or invasion by a foreign body.
see acral lick dermatitis.
modified granulation tissue containing elements of chronic inflammation located adjacent to the root apex of a tooth with infected necrotic pulp.
canine eosinophilic granuloma
see eosinophilic granuloma.
the secondary, progressive, chronic (granulomatous) stage of coccidioidomycosis.
one usually surrounded by a fibrous sac continuous with the periodontal ligament and attached to the root apex of a tooth.
enzootic nasal granuloma

equine dermal granuloma
see swamp cancer.
feline lick granuloma
see feline eosinophilic granuloma complex.
a firm, whitish, fissured, fibrotic granuloma of the gum and buccal mucosa, occurring on an edentulous alveolar ridge and between the ridge and the cheek.
foreign body granuloma
a localized histiocytic reaction to a foreign body in the tissue.
idiopathic sterile g's
occur in dogs and cats; the lesions are painless and may become ulcerated and secondarily infected. An immune-mediated cause is suspected and the lesions often respond to treatment with corticosteroids or other immunomodulating drugs. Sometimes lesions regress spontaneously.
infection by one of the systemic mycotic fungal agents which result in a granulomatous lesion in the skin.
intestinal eosinophilic granuloma
well-delineated, elevated plaques with an eroded surface that occur in a linear pattern, usually on the caudal aspect of the hindleg(s) of cats. Pruritus is variable. Similar lesions may also occur in the oral cavity and on the lips. See also feline eosinophilic granuloma complex.
a granuloma containing lipoid cells; xanthoma.
a granuloma attended by the loss of subcutaneous fat.
see swamp cancer.
one characterized by the arrangement of histiocytes surrounding a focus of fibrin, foreign material, degenerating collagen.
peripheral giant cell reparative granuloma
a pedunculated or sessile lesion of the gingivae or alveolar ridge, apparently arising from the periodontium or mucoperiosteum, and usually due to trauma. It is uncommon in humans and animals. Called also reparative granuloma of the jaw.
pressure point granuloma
see pressure points.
a benign, solitary, nodule resembling granulation tissue, found anywhere on the body, commonly intraorally, usually at the site of trauma as a response of the tissues to a nonspecific infection.
reparative granuloma of the jaw
see peripheral giant cell reparative granuloma (above).
granuloma of the epididymis caused by leakage of spermatozoa from the efferent tubules or the epididymis into surrounding tissue. May be due to trauma, infection or to congenital defects in the duct system.
a large mass containing small abscesses, found in the wall of the uterus of the sow. See also botryomycosis.
a form characterized by numerous dilated blood vessels.
the lesion of tuberculosis and the prototype of granulomatous inflammation. It is composed of histiocytes and epithelioid cells surrounded by giant cells of the Langhans type, lymphocytes and fibroblasts. Bacteria are found in the cytoplasm of the epithelioid and giant cells.
