Bilateral diffuse benign melanocytic tumours of the uveal tract. A clinicopathological study.

In a patient treated for gall-bladder carcinoma bilateral choroidal tumours were clinically interpreted as intraocular metastases. Post mortem histological examination of both eyes revealed a bilateral diffuse benign melanocytic tumour of the uveal tract. The association of bilateral uveal naevi with terminal carcinomas has been reported in seven other cases; it may be a new ophthalmological syndrome.
