Plain-English summary
An 11-year-old male Labrador Retriever was brought in because he had rapidly growing lumps on his leg and near his eye. Unfortunately, the vet found that the dog also had lung metastases (cancer spread) at the time of the first visit. To help relieve his symptoms, the vet performed surgery to remove the leg mass, which was a grade 2 soft tissue sarcoma, and the eye mass, which was a ciliary adenoma. The dog felt better for about 10 weeks but later developed breathing problems and was euthanized 12 weeks after the initial visit due to widespread cancer in his lungs.

Abstract
An 11-year-old, male castrated, Labrador Retriever was evaluated for the presence of rapidly growing concurrent leg and intraocular masses. Metastasis was noted in the chest at time of initial presentation. Indium-111 labeled vitamin B12 imaging was performed, and there was significant uptake by both primary tumors and the lung metastases. Enucleation and amputation were performed for palliative relief. The leg mass was a grade 2 soft tissue sarcoma and the ocular mass a ciliary adenoma. The dog remained symptom-free for approximately 10 weeks before developing signs of respiratory distress. He was euthanized 12 weeks after initial presentation, and there was diffuse infiltration of the lungs with metastatic sarcoma. Indium-111 labeled vitamin B12 imaging identified a ciliary adenoma in this case and may provide a useful differentiation technique for evaluation of intraocular and retrobulbar masses if it can be demonstrated that there is differential uptake between inflammatory or infectious conditions and neoplasia.
