The differential diagnosis of malignant melanoma of the uveal tract
continues to challenge clinicians. In recent decades, we have come to expect
a 95% or better accuracy in the clinical diagnosis of malignant melanoma,
and in some centers such as the Wills Eye Institute, Baltimore, Md,1 and the Mayo Clinic, Rochester, Minn,2
96.3% and 97.7% accuracies, respectively, have been reported. In 1990, a North
American prospective randomized multicenter study group, the Collaborative
Ocular Melanoma Study (COMS) Group, reported a 99.5% accuracy in the diagnosis
of choroidal melanoma.3 By 1998, the COMS
had enrolled more than 2300 eyes into the study, and among the 1532 eyes randomized
and enucleated, 1527 were found to have a choroidal melanoma, resulting in
a diagnostic accuracy of 99.67%.4-6
The 5 misdiagnosed cases included 4 adenocarcinomas that metastasized to the
choroid and 1 choroidal hemangioma. The low misdiagnosis rate in the COMS
is a reflection of . . . [Full Text of this Article]Report of a Case
