The histologic findings of malignant melanoma may be highly variable, and the tumor can mimic many other neoplasms.1 We describe a case of clear cell uveal melanoma. Cytoplasmic clear cell change of uveal melanoma cells can be observed as balloon cells,1 clear cells,2 and signet ring cells.1 The histologic differential diagnosis has to be made with metastatic clear cell carcinomas, seminoma, and clear cell sarcoma as well as xanthomatous cells.
