“…In both studies, vasculitis was not reported. 6,7 In the present case series based on histologic findings and the absence of an etiologic agent, a diagnosis of idiopathic eosinophilic pneumonia with associated vasculitis was made. Interestingly vasculitis has not been described in lungs of horse with eosinophilic pneumonia before this study.…”

Various eosinophilic lesions and their association with diseases have been described in horses. Multisystemic Eosinophilic Epitheliotropic Disease (MEED) characterized by eosinophilic granulomas in various organs represent the most diffuse manifestation. In the present study, we describe the gross and microscopic lesions of idiopathic eosinophilic pneumonia with associated pulmonary vasculitis in 11 horses without systemic involvement. Lungs were enlarged, pale pink, poorly collapsed with white-reddish nodules, randomly distributed throughout the parenchyma. Histologically the lesions ranged from mild eosinophilic bronchointerstitial pneumonia to severe eosinophilic lobular bronchopneumonia associated with eosinophilic necrotizing vasculitis affecting small to medium-size vessels. There was no histologic evidence of parasites within the lesion of any of these horses. Eosinophilic pneumonia with vasculitis and without intralesional parasites have not been previously reported in horses. The current histologic findings are similar to pathologic lung findings observed in Churg-Strauss syndrome of man.

“…Based on the above described similarities, some researchers have even suggested that ICEP may be an early form of MEED (Uhlhorn et al . ). However, it has been reported that cases of ICEP in horses commonly present with a peripheral eosinophilia (Bell et al .…”

“…Given the radiographic appearance, neoplasia, granulomatous pneumonia and EMPF could not be fully ruled out although the identification of the eosinophilic inflammation in the BALF and lung tissue supported ICEP as more likely even though the horse in the present case did not exhibit peripheral eosinophilia as has been reported previously in horses with ICEP (Uhlhorn et al . ; Bell et al . ).…”

Pulmonary and hepatic eosinophilic granulomas and epistaxis in a horse suggestive of multi‐systemic eosinophilic epitheliotropic disease

Multi-systemic eosinophilic epitheliotropic disease (MEED) is a relatively uncommon disease characterised by eosinophilic infiltration of more than one organ system, with the skin and gastrointestinal tract most commonly affected. This case report describes a gelding that presented for weight loss, increased respiratory rate and effort and chronic intermittent epistaxis. During post mortem examination diffuse eosinophilic granulomatous lesions were identified in the lung and liver, leading to a diagnosis of MEED. Veno-occlusive pulmonary remodelling was also discovered, believed to be the cause of the chronic epistaxis and a result of the pulmonary fibrosis and eosinophilic granulomas.
