Purpose To demonstrate the clinical pathologic correlation in a hemorrhagic choroidal melanoma. Observations A 52 year old patient presented with a large choroidal mass associated with vitreous and retinal hemorrhage. The eye was enucleated and histopathology demonstrated epithelioid-type MART1 positive tumor cells consistent with choroidal melanoma. The tumor had broken through Bruch's membrane, which led to localized vascular compression with bleeding into the subretinal space, retina and vitreous. Conclusions and importance Choroidal melanoma rarely presents with hemorrhage. Tumor rupture through Bruch's membrane may result in a tourniquet effect on the tumor vasculature leading to massive hemorrhage, as in this case. A high level of clinical suspicion is required to make the diagnosis.
