[Malignant melanoma in two cats].

Malignant melanomas with extensive metastasis in various organs were diagnosed in a 8-year-old European shorthair cat and a 10-year-old Persian cat. The primary tumor in the European shorthair cat was located within the eye. The clinical progress, gross pathology and histology are outlined. The possibility of an increase of melanomas in combination with FIV- or FeLV-infections is discussed.
