Feline eosinophilic granuloma complex (EGC), a dermatologic reaction pattern in cats, frequently develops secondary to a primary disease, the most common being allergic hypersensitivities (e.g. fleabite, cutaneous adverse food reaction, environmental, mosquito bite). Additional proposed causes involve infectious agents (i.e. bacteria, viruses, dermatophytes, parasites),¹ with rare cases being reported as idiopathic. Lesions may present as eosinophilic plaques, eosinophilic granulomas, and indolent ulcers. Although mosquito bite hypersensitivity has not classically been considered part of the EGC, some dermatologists believe it may be a manifestation of that complex.²
