Summary
This case report details a rare instance of concurrent choroidal melanoma in a father and son. The probability of such familial uveal melanoma is exceptionally low, estimated at 1 in 10 million.
Area of Science:
- Ophthalmology
- Oncology
- Genetics
Background:
- Uveal melanoma is the most common primary intraocular malignancy in adults.
- Familial occurrence of uveal melanoma is exceedingly rare, with limited documented cases.
Observation:
- A 41-year-old son was diagnosed with unilateral choroidal melanoma.
- Three months later, his 68-year-old father presented with a rapidly growing pigmented choroidal mass, also diagnosed as uveal melanoma.
Findings:
- No personal or family history of atypical moles, cutaneous melanoma, or other malignancies was reported in either individual.
- The statistical likelihood of familial uveal melanoma in a father-son pair was calculated to be approximately 1 in 10 million, highlighting the extreme rarity of this event.
Implications:
- This case underscores the possibility of familial predisposition to uveal melanoma, despite its low statistical probability.
- Further research into potential genetic factors or shared environmental influences may be warranted for understanding rare familial cancer syndromes.
