[Orange pigment and hyperfluorescent pin-point dots on the angiographic datas of malignant melanoma (author's transl)].
In a 65 year old woman, a melanoma has been diagnosed on the following angiographic datas: relief; irregular pigmentation; hyperpigmented border-line; leakage of the dye; orange pigment; hyperfluorescent pin-point dots over the tumor. These last two materials has been histologically studied. It is confirmed that lipofuscin could be the constituant of the orange pigment and that the hyperfluorescent points could correspond with exsudative, hyaline and glyco-lipido-proteic "blebs", in connection with the Bruch's membrane or in the subretinal space. This could be the expression of choriocapillaris and/or RPE suffering.
