Primary ocular melanoma in dogs.
The clinical signs, gross and microscopic appearance, treatment, and follow-up results of 35 dogs with primary ocular melanomas are reviewed. The melanomas are classified as epibulbar or intraocular based on the site of origin. The intraocular tumors are classified as spindle A, spindle B, mixed spindle B and epithelioid, and purely epithelioid based on cytologic criteria. The pathologic findings are matched with the follow-up history in an attempt to determine which features have prognostic significance. The findings are contrasted to those of similar studies of spontaneous ocular melanomas in man.
