Clinical approach to feline eosinophilic granuloma complex

CATS frequently present with various manifestations of the so‐called eosinophilic granuloma complex (EGC). Many cases are considered to have an underlying allergic aetiology, especially those with recurrent and multiple lesions. Allergic causes include fleas and other insects and, occasionally, environmental and dietary antigens may be implicated. Initial investigations may include skin cytology, scrapes for ectoparasites and skin biopsy; in chronic cases, the clinician has to evaluate possible allergen exposure and, particularly, the effectiveness of flea control measures. Numerous types of medication have been recommended for chronic cases, but compliance with oral products is often poor and this syndrome of eosinophilic skin disease remains a therapeutic challenge for both owners and their veterinary surgeons. This article describes the key diagnostic features of EGC and discusses the options available for therapy.
