Summary
Bilateral uveal melanoma is rare. This case highlights the need for vigilant monitoring of the second eye, especially after genetic analysis revealed distinct chromosomal abnormalities in each tumor.
Area of Science:
- Ophthalmology
- Oncology
- Genetics
Background:
- Bilateral uveal melanoma is an exceptionally rare clinical diagnosis.
- This report details the first documented case of bilateral choroidal melanoma in Austria.
Observation:
- A 62-year-old male presented with sequential choroidal melanomas in both eyes.
- The left eye melanoma required enucleation after multiple treatments, while the right eye was treated with ruthenium-106 brachytherapy.
- Despite initial treatment success, the patient developed metastatic disease and succumbed to liver metastasis.
Findings:
- Genetic analysis revealed monosomy 3 in both melanomas.
- The right eye melanoma exhibited an amplification of c-MYC on chromosome 8, which was absent in the left eye melanoma.
- The patient developed metastatic disease despite no initial signs of metastasis.
Implications:
- This case underscores the critical importance of thorough and ongoing examination of the contralateral eye in cases of uveal melanoma.
- The distinct genetic findings (monosomy 3 and c-MYC amplification) in each eye warrant further investigation into their prognostic and therapeutic significance.
- Understanding the genetic landscape of bilateral uveal melanoma may lead to improved diagnostic and treatment strategies.
