Introduction
Indolent ulcer is one of eosinophilic granuloma complex
(EGC). Other similar name are feline eosinophilic
granuloma, eosinophilic granuloma ulcer of cats, rodent
ulcer. Indolent ulcer is unilateral or bilateral erosive lesion
on the upper lip of cat of any age (5). The lesion on lower
lip is uncommon. The lesions vary in size from a few
millimeters up to several centimeters, and may be affected
the margin of the upper lips. The cause of indolent ulcer is
unknown. The presence of eosinophils suggests an allergic
reaction, parasite problem, or immune problem. Recently
emerging evidence shows a possible genetic predisposition
in some cats to develop lesion when exposed to allergic
triggers , particularly fleas. Eosinophilic granuloma
complex (EGC) are well described in cats in three forms
of cutaneous lesions patterns : 1) indolent ulcers. 2)
eosinophilic plaque and 3) eosinophilic granuloma.
EGC is a one of hypersensitivity of immune system.
Hypersensitive immune system is one which overreacts to
a stimulus (3). Definitive diagnosis of EGC must be made
on histopathology. (2) Typical histopathological features
that are described include eosinophilic inflammation and
becomes a mixed granulomatous inflammatory reaction.
The aim of this case report was to describe diagnostic
method and treatment outcome of indolent ulcer on upper
lip in a cat.
