Primary ocular hemangiosarcoma in a dog

Abstract

AbstractA 10‐year‐old, male, neutered Boxer dog had an ulcerated mass covering nearly 90% of the left cornea. The dog had a 1year and 5months history of a previously removed left corneal hemangiosarcoma before clinical presentation. Visualisation and evaluation of the anterior chamber and internal ocular structures could not be performed because of the severe extension of the ocular mass. Enucleation of the left eye (OS) with extensive removal of the associated soft tissue was performed and submitted for histological examination. Histological findings confirmed corneal hemangiosarcoma with neoplastic extension to the limbus/conjunctiva. Corneal hemangiomas and hemangiosarcomas are rare in all domestic species. In dogs, a definitive cause for the development of corneal hemangiosarcomas is still undetermined. However, it is speculated that increased exposure to solar radiation and chronic inflammation‐inducing neovascularisation are predisposing factors. There was no evidence of mass recurrence or metastasis after 5 months of follow‐up.
