Eosinophilic fasciitis in a rhesus macaque

Abstract
Eosinophilic fasciitis (EF) is an inflammatory disorder in the category of scleroderma‐like connective tissue diseases. There are no animal models for spontaneously occurring EF. We present the case of a rhesus macaque (Macaca mulatta) with clinical, laboratory, and histologic features of EF.
