This enucleation specimen demonstrates an amelanotic, mushroom-shaped, slightly hemorrhagic tumor near the optic nerve (arrow). True retinal detachment is present, and the retina is folded (arrowhead). The subretinal fluid is hazy (*).

Fundus photograph of a 69-year-old male with an amelanotic choroidal melanoma and corresponding exudative retinal detachment. Transvitreal biopsy was performed at the time of radioactive I-125 plaque placement. The genetic expression profile revealed a Class 1A, PRAME negative tumor.

This case highlights an amelanotic melanoma, an atypical presentation of a choroidal melanoma lacking the characteristic pigmentation. These lesions can easily be mistaken for choroidal hemangiomas, metastases, or inflammatory masses. Clinically, the lesion appears as a dome-shaped, yellowish subretinal mass, often associated with subretinal fluid, lipofuscin deposition, or retinal detachment. The absence of pigment can delay diagnosis, making multimodal imaging essential. Diagnostic tools: • B-scan ultrasound: low to medium internal reflectivity • OCT: overlying subretinal fluid and RPE elevation • FAF: orange pigment and RPE disruption • ICG/FA: variable, often hypofluorescent core Important: Prompt referral to ocular oncology is critical for management and prognosis.

This FAF image reveals a hypoautofluorescent mass with areas of dense hyperautofluorescent stippling—a classic pattern suggestive of an amelanotic choroidal melanoma. Amelanotic melanoma is a rare variant of uveal melanoma, accounting for only a minority of cases. Unlike pigmented melanomas, these lesions lack melanin, making them more challenging to detect on conventional color fundus imaging. FAF Characteristics: • Central hypoautofluorescence: due to loss or compression of the RPE • Peripheral hyperautofluorescent speckling: consistent with lipofuscin accumulation or RPE disruption • Often associated with subretinal fluid or orange pigment seen clinically Location: Juxtapapillary, with potential optic nerve involvement—a factor that complicates both diagnosis and

Leiomyoma is a benign, smooth muscle tumor. Ninety percent of cases occur in women. The differential diagnosis includes amelanotic melanoma and nerve sheath tumors. This transversal pupil–optic nerve (PO) section of an enucleation specimen shows a nodular, well-delineated, whitish tumor in the ciliary body. The cut surface shows small foci of hemorrhage without necrosis. The retina partially covers the inner surface of the tumor, and the sclera is not infiltrated. Note the slightly displaced (subluxated) cataractous lens and the choroidal detachment artifact in the right inferior corner.
