Suspected latent vertebral metastasis of uveal melanoma in a dog: a case report.
A six-year-old intact male Pomeranian was examined because of right eye discomfort. An iris neoplasm was suspected and the eye was enucleated. A uveal melanoma with malignant features was diagnosed. The dog recovered uneventfully from surgery. A general physical examination was performed at 3-month intervals afterwards without any detectable problem, but 18 months after the first presentation the dog suffered a rapid, progressive paraplegia. Radiographic examination and myelography revealed a spinal cord compression at the level of the 8th thoracic (T8) vertebral body. Surgical exploration of the area revealed a potential vertebral neoplasm: histopathology confirmed a melanoma which was suspected to have resulted from metastasis from the previously diagnosed uveal melanoma.
