An 11-year-old male, neutered European cat was presented for anisocoria due to pupillary dilation in the right eye. Ophthalmic findings were restricted to this eye and consisted of a raised, darkly pigmented, retrolental mass associated with retinal detachment. Ultrasonography identified the mass lesion protruding into the vitreous cavity from the posterior pole of the eyeball and confirmed the detachment of the retina. A tentative diagnosis of an intraocular tumor was made. Radiographic evaluation and retromandibular lymph node cytology did not reveal evidence of distant metastasis. Orbital exenteration of the affected eye was performed and the tumor was diagnosed as a choroidal melanocytic tumor with no criteria of malignancy (melanocytoma). The cat died 5 months later from renal lymphoma, and necropsy did not detect metastasis of the melanocytic tumor. To our knowledge this is the first reported case of feline choroidal melanocytoma.
一只11岁已绝育的欧洲雄性猫因右眼瞳孔散大导致的瞳孔不等大前来就诊。眼科检查结果仅限于该眼，表现为一个隆起的、色素沉着较深的晶状体后肿块，伴有视网膜脱离。超声检查发现肿块从眼球后极突入玻璃体腔，并证实了视网膜脱离。初步诊断为眼内肿瘤。影像学评估和下颌后淋巴结细胞学检查未发现远处转移的证据。对患眼进行了眼眶内容物剜除术，肿瘤被诊断为无恶性标准的脉络膜黑素细胞瘤（黑素细胞瘤）。这只猫5个月后死于肾淋巴瘤，尸检未发现黑素细胞瘤转移。据我们所知，这是首例报道的猫脉络膜黑素细胞瘤病例。
