Fluoroangiographic and echographic study on a juxtapapillary hamartoma of the retinal pigment epithelium.

A patient with a juxtapapillary hamartoma is described, in consideration not only for the scarcity of such cases described in the literature, but also for the clinical and echographic characteristics that were observed for the involvement of the right eye, and because the patient was female. Echography and especially standardized A-scan echography, showing a lesion at high reflectivity without acoustic shadowing, allowed us to exclude the presence of a malignant melanoma and retinoblastoma, and directing us to the diagnosis of a malformation of angiomatous type.
