Simultaneous bilateral primary diffuse malignant uveal melanoma: case report with pathological examination.

S Tsukahara, K Wakui, S Ohzeki

    The British Journal of Ophthalmology
    |January 1, 1986

    Summary

    A rare case of bilateral diffuse malignant melanoma affecting the choroid, ciliary body, and iris led to blindness. This suggests a potential tumor-producing tendency in patients with a history of malignancy.

    Area of Science:

    • Ophthalmology
    • Oncology

    Background:

    • Bilateral diffuse malignant melanoma of the uvea is a rare and aggressive ocular tumor.
    • This case highlights the importance of considering systemic factors in ocular malignancies.

    Observation:

    • A 50-year-old woman presented with sudden vision loss, night blindness, and painful eyes.
    • Clinical examination revealed reduced visual acuity, retinal pigment epithelium atrophy, and retinal detachments.
    • Electroretinogram showed reduced amplitude, consistent with widespread retinal dysfunction.

    Findings:

    • Histopathological examination confirmed diffuse infiltration of the choroid, ciliary body, and iris by malignant melanoma cells.
    • The patient had a prior history of treated uterine carcinoma, suggesting a possible tumor-producing tendency.

  • The bilateral and likely multicentric origin of the ocular tumors was noted.

    • Implications:

    • This case underscores the potential for systemic factors and a predisposition to malignancy in rare ocular tumors.
    • Early detection and a comprehensive approach are crucial for managing such aggressive conditions.
    • Further research into the genetic and systemic factors associated with diffuse uveal melanomas is warranted.
