Case Report on Diffuse Amelanotic Choroidal Melanoma Mimicking Metastasis

One detailed case report describes an 82-year-old male patient with dual primary malignancies and a rare ocular tumor. The report, authored by figshare admin karger and last updated in 2026, includes multimodal imaging findings and biopsy results. It highlights the diagnostic challenge of distinguishing diffuse amelanotic choroidal melanoma from metastatic disease.

Use Cases

• Study the clinical presentation of diffuse amelanotic choroidal melanoma based on the detailed case description.
• Analyze diagnostic challenges in ocular oncology based on the differential diagnosis between melanoma and metastasis.
• Review pathological findings of optic nerve invasion and extrascleral extension based on the enucleation results.
• Investigate multimodal imaging applications in ambiguous ocular tumor cases based on the described diagnostic process.

Strengths

• Includes detailed clinical history of a patient with dual primary malignancies.
• Provides specific pathological findings, including mixed cell-type melanoma and optic nerve invasion.
• File size is 1.1 MB, indicating a contained document.

Limitations

• Contains a single case report, limiting statistical power and generalizability.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
