Plain-English summary
A 10-year-old Labrador Retriever was brought in for an eye issue, and a mass was found in the right eye that was pressing against the lens. After the eye was removed for further examination, it was discovered that the dog had a ciliary body adenocarcinoma, a type of eye tumor, that had invaded the lens. This is the first known case of such a tumor affecting the lens in dogs. Unfortunately, the outcome for this dog isn't mentioned, but treatment typically involves removing the affected eye to prevent further complications.

Abstract
Ciliary body adenocarcinomas are well-recognized tumors in dogs; however, invasion of the lens by the tumor has not been described in veterinary species. Evaluation of the right eye of a 10-year-old Labrador Retriever revealed a ciliary body mass spanning from the 10 o'clock to 2 o'clock position that was impinging on the lens. Histologic evaluation of the enucleated eye revealed a ciliary body adenocarcinoma with lens invasion. Where the tumor encroached on the lens, the lens capsule was absent and there was scrolling of the broken ends of the capsule. Tumor cells were juxtaposed to the lens fibers and dissecting between the lens fibers. There were no inflammatory cells within the lens associated with the breaks in the capsule or within the anterior chamber. To our knowledge this is the first report of lens invasion by a tumor in any veterinary species.
