CLINICAL EXAMINATION
In cats with eosinophilic plaque, the lesions are usually located on the ventral abdomen and medial aspects of the thighs.

Uncommonly, lesions may appear on the feet, which usually present with crusting, exudation, erythema and swelling of the plantar or the interdigital skin (Fig. 36.1).
Other variants of the eosinophilic granuloma complex may be found on the same individual, e.g. ‘linear granuloma’, which is seen as a raised chord-like linear plaque, with a yellowish surface, on the caudal aspect of the thighs (Fig. 36.2).
