Abstract

•Presentation, findings, and outcome of a large eosinophilic granuloma.•Granuloma caused lameness, bony remodeling, and soft tissue swelling.•Sulfur granules were present in the center of the lesion.•Primary differential was habronemiasis, but no larvae were found.•Despite dramatic clinical presentation, cosmetic and functional outcome is excellent.

A mare presented with lameness and a large swelling palmarolateral and proximal to the right carpus. Radiography revealed mineral opacity, bone remodeling, and soft tissue swelling. At surgery, fibrous tissue was removed from the subcutaneous area and sulfur granules were removed from near the carpal canal. Histopathology revealed eosinophilic inflammation. Habronemiasis was the primary differential, although no larvae were found. The swelling resolved, and the mare was sound 1 year after initial presentation.
