Malignant melanomas of the uveal tract in children and young adults.

The Wills Eye Hospital experience with 17 cases of malignant melanoma of the uvea affecting children and young adults was reviewed. They did not appear to differ clinically or histologically from uveal melanomas in older patients, except that in most cases there was a considerable delay in diagnosis, perhaps reflecting a lack of clinical suspicion. Ancillary diagnostic techniques, such as fluorescein angiography, ultrasonography, and 32P studies were often helpful in arriving at the correct diagnosis once the lesion was suspected and referred for evaluation. Malignant melanoma of the uveal tract is not exclusively a disease of old age, and this diagnosis should not be excluded on the basis of the patient's age alone.
