Plain-English summary
A 6-year-old mare was brought in with a red mass in the conjunctiva (the tissue covering the eye) of her left eye. After a thorough eye examination, the veterinarian removed the mass for further testing. The results showed that it was a benign growth called intravascular papillary endothelial hyperplasia, which is not cancerous. The mare is expected to recover well after the removal of the lesion.

Abstract
OBJECTIVE: Vascular tumors of the conjunctiva in the horse are rare. We present a unique case of an intravascular papillary endothelial hyperplasia of the conjunctiva. ANIMAL STUDIED: Horse. PROCEDURES: Case report. A 6-year-old-mare presented with a red mass in the conjunctiva of the left eye. After complete ophthalmologic examination the lesion was excised. The tissue was processed for light microscopy and studied histopathologically. RESULTS: Pathologic examination revealed a nonencapsulated vascular lesion composed of confluent vascular spaces filled by multiple papillary structures composed of a central collagenous core lined by hyperplastic endothelial cells. There was neither atypical endothelial cell nor mitotic activity. CONCLUSIONS: Intravascular papillary endothelial hyperplasia is a benign proliferative lesion that should be differentiated from malignant vascular tumors.
