In its early stages a hematoma beneath the retinal pigment epithelium is said to simulate a malignant melanoma of the choroid more closely than any other lesion.1-3 These hematomas are characterized clinically by the sudden onset of visual loss associated with a dark, rounded thickening at the posterior pole. The hemorrhagic nature of the lesion usually becomes evident within ten days to two weeks after onset, as it begins to clear, or as hemorrhage appears at its edges.
This report concerns a case in which a dark, elevated tumor appeared several weeks after the discovery of a hemorrhagic lesion in the macular area. The rapid appearance of this dark mass, which increased in size and became elevated, led to a clinical diagnosis of malignant melanoma of the choroid, and the eye was enucleated.
