Osseous choristoma of the choroid. A familial disease
S. L. Cunha
Two patients in the same family (daughter and mother) had osseous
choristoma of the choroid in four otherwise normal eyes. The clinical
diagnosis of the choroidal lesion was confirmed by B-scan ultrasonography.
Both patients were followed up for five years and neither showed any
essential change of the fundus. The high prevalence of this choroidal tumor
in girls and women (20 of 22 reported cases) and the present report on two
patients in the same family suggest that a hereditary factor should be
considered in the etiology of this unusual choroidal lesion.
