Abstract:
Ultrastructural study, by Scanning and Transmission Electron Microscopy, of three choroidal melanomas allows us to depict main features and cellular types of melanomas and to discuss our results with precedent studies. One case of balloon-cell tumor shows an unusual (from unknown genesis) substance, intra- or extracellularly located, but always near pigment cells expansions.
