cartilaginous eosinophilic streaks

streaks of eosinophilic matrix in cartilage. Some are normal zones of development, others represent areas of matrix degeneration and osteochondrosis.

eosinophilic chemotactic factor

a primary mediator of type I anaphylactic hypersensitivity, it is an acidic peptide (molecular weight 500) released by mast cells, which attracts eosinophils to areas where it is present.

equine eosinophilic chronic dermatitis

acanthosis and hyperkeratosis accompanied by eosinophilic granulomas in pancreas and other epithelial organs.

feline eosinophilic granuloma complex

a collective name given to the lesions of eosinophilic ulcer, eosinophilic plaque (below), and linear granuloma because of similarities in histopathology, clinical course and occasionally simultaneous occurrence in the cat.

eosinophilic granuloma

nodules or plaques that occur on skin or oral mucosa of dogs. Usually not pruritic, but oral lesions can cause some difficulties in eating. The cause is unknown. See also feline eosinophilic granuloma complex (above), equine nodular collagenolytic granuloma.

eosinophilic intestinal granuloma

see angiostrongyluscostaricensis.

eosinophilic lung disease

see pie syndrome.

eosinophilic meningitis

see gnathostomaspinigerum.

eosinophilic meningoencephalitis

see sodium chloride poisoning, angiostrongyluscantonensis.

eosinophilic myocarditis

in cattle may be observed in normal animals at slaughter. Histologically there is a predominant eosinophil invasion of the heart muscle. May be accompanied by similar lesions in skeletal muscles.

eosinophilic plaque

well-defined, raised, ulcerated and extremely pruritic lesions that occur on the skin of cats, usually on the abdomen or hindlegs. There are large numbers of eosinophils present in the dermis and sometimes peripheral blood. See also eosinophilic granuloma (above), feline eosinophilic granuloma complex (above).

eosinophilic pneumonia

see pie syndrome.

eosinophilic ulcer

a well-defined ulceration, usually on the upper lip of cats overlying the canine tooth, which is shallow initially but can become extremely erosive and sometimes neoplastic. Mildly irritating to the cat. Called also indolent ulcer, rodent ulcer. See also feline eosinophilic granuloma complex (above).
