—The report in the April issue of the Archives by Drs. Shields and Font, "Melanocytoma of the Choroid Clinically Simulating a Malignant Melanoma" (87:396-400, 1972), was noted with great interest. Once again, the vagaries in clinical diagnosis of malignant melanoma of the choroid are amply demonstrated, and the authors rightly cite Ferry's classic article which demonstrated that approximately one eye out of five removed with the clinical diagnosis of malignant melanoma of the choroid does not, in fact, contain a tumor.We should like to make a plea for more widespread use of the radioactive phosphorus (32P) uptake test in any patient in whom enucleation for a presumed malignancy is contemplated.1,2 We have had experience now with over 150 cases studied with 32P, of which approximately 125 had "positive" tests. Almost all of the eyes with a positive 32P test have been enucleated
