Five cases of a rare type of malignant melanoma of the choroid with a typical clinical and histopathological picture are reported. This tumour is characterized by its location near the optic disk, its early growth through the retina, its structure with bloodless and blood‐filled cavernous spaces, and its manifestation by a massive haemorrhage into the vitreous. “Historical” cases are mentioned, showing that this rare tumour, occurring in about 1:250 of malignant melanomas of the choroid, has a Scandinavian tradition. The clinical and histopathological details are discussed.
