Summary
This study reports two rare cases of intraocular melanoma metastases from skin cancer, presenting unusual features and delayed onset. Ocular melanoma requires careful monitoring due to potential for aggressive progression and varied clinical presentations.
Area of Science:
- Ophthalmology
- Oncology
- Dermatology
Background:
- Metastatic melanoma to the eye presents unique diagnostic and management challenges.
- Primary cutaneous malignant melanoma can metastasize to the eye years after initial treatment.
Observation:
- Two cases of intraocular metastases from primary cutaneous malignant melanoma are detailed, with latencies of 5 and 16 years.
- The first case involved tumor invasion of the chamber angle leading to secondary glaucoma and scleral extension, necessitating enucleation despite radiation therapy.
- The second case presented as a probable melanoma metastasis detected during vitrectomy, with subsequent growth observed via ophthalmoscopy and ultrasonography, confirmed by histology to involve retina, choroid, and optic nerve.
Findings:
- Intraocular melanoma metastases can manifest with diverse and unusual clinical features.
- Delayed presentation of ocular metastases from cutaneous melanoma is possible.
- Aggressive tumor progression, secondary glaucoma, and involvement of multiple ocular structures can occur.
Implications:
- These cases highlight the importance of vigilance for delayed ocular metastases in patients with a history of cutaneous melanoma.
- Ocular melanoma metastases require tailored management strategies, potentially including surgical intervention, laser therapy, and systemic treatment.
- Further research into the mechanisms and optimal treatment of intraocular melanoma metastases is warranted.
