6년령 중성화 수컷의 말티즈가 서울대학교 부속 동물병원에 내원하였다. 안검사 상 우안의 전방출혈 및 안방수 흐림이 확인되었으며 포도막염에 대한 치료가 진행되었다. 4개월 후 우안 홍채의 등쪽 측면의 전방변위가 확인되었으며 안초음파 검사상 모양체 유래의 종괴로 잠정 진단되었다. 흉부 및 복부 영상검사에서는 종양의 전이소견이 발견되지 않았다. 이후 지속적인 포도막염과 종괴의 종대로 인해 우안의 안구 적출을 실시하였다. 조직병리학적 검사에서 우안의 종괴는 만성적인 출혈을 동반한 전포도막 흑색세포종으로 확진되었다. 본 증례와 같이 안내 종양 환자에서 비수술적인 처치로 눈의 지속적인 출혈이나 염증이 호전되지 않는 경우, 안구적출을 통한 적절한 안내 종양의 제거가 고려되어야 한다.

A 10-year-old spayed female beagle dog presented with a 2-month history of third-eyelid elevation in the left eye (OS). Ophthalmic examination revealed slightly diminished corneal and palpebral reflexes along with exophthalmos in the OS. Schirmer's tear test and intraocular pressure values were within the normal range for the OS. Slit-lamp biomicroscopy revealed protrusion of the third eyelid and corneal opacity in the OS. Fundoscopy revealed a prominent black mass in the OS covering the optic nerve. Tapetal hyper-reflectivity was also observed around the mass. Ocular ultrasonography showed a 0.74 × 0.67 cm echogenic posterior segment mass around the optic nerve protruding into the retrobulbar space. Computed tomography revealed a contrast-enhanced soft tissue lesion in the posteromedial aspect of the left eyeball protruding into the retrobulbar region, and the optic nerve was suspected to be involved. No evidence of osteolytic changes in the adjacent bone or distant metastasis was observed. Enucleation was performed to prevent potential metastasis or local invasion of the mass and to relieve discomfort due to exposure to keratopathy resulting from lagophthalmos. Histopathological examination revealed a central choroidal melanocytoma extending into the optic nerve. No local recurrence was detected until 16 months postoperatively.

A 13-year-old spayed female Beagle dog was referred with high intraocular pressure, hyperemia, and exophthalmos of the left eye and underwent ultrasound, which revealed a mass in the ciliary body of the left eye. Magnetic resonance (MR) imaging was ordered to evaluate invasion of surrounding structures and metastasis to the brain via the optic nerve. On MR imaging, a single, well-defined, smoothly marginated, triangular-to-oval-shaped mass was found. The mass was hyperintense on T1-weighted images and hypointense on T2-weighted images, similar to a previous case of ocular melanoma. The mass originated from the ciliary body and extended from the anterior chamber to the posterior chamber. Slight enhancement was observed in the mass. There was no evidence of invasion into surrounding structures or the optic nerve, and no sign of metastasis to the brain. The mass was histopathologically diagnosed as benign uveal melanocytoma.
