[Feline ocular melanoma. Clinical and pathologico-anatomic findings in 37 cases]

The clinical and pathological findings of 37 feline ocular melanomas are described. The majority of the tumors examined were diffuse iris-ciliary body melanomas of epithelioid and pleomorphic (anaplastic) cell type with numerous mitotic figures. The majority of the tumors showed invasion of the anterior sclera. Metastases were found in three cases predominantly in the abdominal viscera (liver). The clinical diagnostics as well as the differential diagnosis, therapy and prognosis of feline uveal melanoma are presented. The causal pathogenesis is discussed comparatively.
