- Choroidal Tumor
- Choroidal melanoma is often asymptomatic and diagnosis is incidental. The tumors may grow beneath the retina, or may break through the Bruch membrane and disrupt the retina. Tumors breaking through the Bruch membrane and disrupting the retina have a characteristic “mushroom” shape. This enucleation specimen shows a melanotic, dome-shaped choroidal tumor (arrow). There is partial retinal detachment with underlying subretinal fluid in the area opposite the tumor (*) and slight macular edema in the posterior pole (seen in the central area of the image).
