Angioinvasive Metastitic Squamous Cell Carcinoma (13 year old DSH)

This cat was present for evaluation of a previously excised and diagnosed conjunctival squamous cell carcinoma. This fundus photograph of that eye shows abnormal pigmentation and gray infiltrates beneath a retinal detachment, marked by the arrows. Tumor cells extended with luminal blood vessels deeply into the choroid and retina. A presumed pulmonary mass was also identified radiographically.
