Small choroidal melanoma with monosomy 3.

AbstractPURPOSE:
To report a patient with small juxtapapillary choroidal melanoma with chromosome 3 monosomy treated with I(125) plaque and transpupillary thermotherapy (TTT). A 64-year-old Caucasian male presented with painless blurred vision of the left eye. Ocular examination disclosed a small juxtapapillary choroidal melanocytic tumor with overlying subretinal fluid and orange pigment. Ultrasound showed an elevated choroidal mass of 2 mm thickness with low reflectivity on A-scan and hollowness on B scan, consistent with a small choroidal melanoma. The patient was treated with plaque I(125) radiotherapy combined with one session of TTT. Genetic testing of the tumor cells obtained by fine needle aspiration biopsy showed chromosome 3 monosomy. At 1 year after treatment, the tumor was regressed with resolution of subretinal fluid and 20/40 visual acuity. A small choroidal melanoma can manifest monosomy of chromosome 3, a known predictive factor for the development of systemic metastasis.
