20 experimental amelanotic Greene melanomas implanted into the anterior chamber of rabbit eyes were examined immunohistochemically in paraffin sections. All the Greene melanomas were found to be positive for vimentin, S-100 and HMB 45 and negative for alpha-human chorionic gonadotropin, neuron-specific enolase, chromogranin, synaptophysin, cytokeratin, carcino-embryonic antigen, serotonin, desmin and pan leukocyte marker T-200. Greene melanoma is comparable with human cutaneous and uveal melanoma in its immunohistochemical reaction pattern.
