 Purpose:To describe a case of rapidly progressive malignant melanoma. Case and Findings:A 68-year-old woman presented with corrected visual acuity of 0.5 right and 1.2 left. Her right eye showed an elevated and pigmented lesion of 3 disc diameters near the optic disc. The tumor rapidly enlarged during the next 6months and developed vitreous hemorrhage. Ultrasonography showed the tumor to be mushroom-shaped. Biopsy during surgery showed malignant melanoma and led to enucleation. The tumor invaded the retina through the Bruch's membrane. It was identified as epithelioid type malignant melanoma. Conclusion:Epithelioid type choroidal malignant melanoma is infrequent. This case illustrates that it may undergo rapid progression.
