Diffuse melanoma of the choroid

D H Char, R D Stone, J B Crawford

    The British Journal of Ophthalmology
    |March 1, 1980
    PubMed
    Summary

    Diffuse melanoma of the uvea is challenging to diagnose and often presents with early extrascleral extension. This condition carries a poorer prognosis compared to other uveal tract melanomas.

    Area of Science:

    • Ophthalmology
    • Oncology

    Background:

    • Uveal melanoma is a rare intraocular malignancy.
    • Accurate diagnosis and staging are crucial for patient outcomes.

    Observation:

    • An 81-year-old woman initially diagnosed with minimally active melanoma was found to have a diffuse melanoma.
    • The tumor exhibited extrascleral extension.

    Findings:

    • Diffuse melanomas of the uvea present diagnostic challenges.
    • These tumors are characterized by frequent and early extrascleral extension.
    • Diffuse uveal melanomas have a poorer prognosis than typical uveal tract melanomas.

    Implications:

    • Highlights the importance of considering diffuse melanoma in the differential diagnosis of uveal lesions.
    • Emphasizes the need for advanced imaging and potentially earlier intervention for diffuse uveal melanomas.
    • Suggests that current diagnostic and treatment paradigms may require adjustment for this specific subtype.
