Consecutive choroidal melanoma in the same eye of a patient.

PURPOSE: To report the occurrence of two entirely separate choroidal melanomas in the same eye of one patient.

DESIGN

Observational case report.

METHODS

Retrospective case report from one clinical practice. Two choroidal melanomas were observed to develop in the same eye of one patient.

RESULTS

An inferonasal choroidal melanoma was diagnosed in the left eye of a 30-year-old woman in 1990. This was successfully treated with proton beam radiotherapy. In 1996, a superotemporal choroidal tumor in the same eye was observed to grow rapidly and it was treated with a ruthenium plaque in 1996. There was a history of cutaneous malignant melanoma.

CONCLUSIONS

It is extremely rare for two choroidal melanomas to develop in one eye, and there may be a genetic predisposition.
