[A case of primary giant malignant melanoma of the eye with extraocular extension].

A 57-year-old male patient presented to the ophthalmology department with right eye pain, swelling, and epiphora. He was initially diagnosed with a right orbital mass, right globe rupture, and possible choroidal melanoma. MRI revealed abnormal signals in the right vitreous body. Under general anesthesia, the patient underwent right eye enucleation. Intraoperatively, opening the globe revealed a large grayish-black mass. Pathological examination confirmed choroidal melanoma. Postoperatively, the patient was transferred to the oncology department for prevention of orbital tumor recurrence and metastasis.
