Histology of small melanomas

Abstract
In a series of 193 choroidal melanomas we collected the histological data of 25 small and 31 medium-sized tumours enucleated on the basis of the results of the 32P-test. Thirty four (34%) percent showed epithelioid cells and 70% showed scleral involvement, both percentages being higher than in most reports. We do not advocate observation and delay of treatment in case of small melanomas until growth is established clinically.
