Extremely rapid growth of a primary choroidal melanoma

A small, minimally elevated, nonpigmented choroidal tumor increased in volume 12-fold and grew from the edge of the fovea to the optic disk within 60 days. Histopathology of the enucleated globe demonstrated a mixed spindle and epithelioid cell malignant melanoma with numerous mitotic figures. The calculated doubling time of this tumor was 17 days.
