Bilateral Diffuse Malignant Melanoma of the Uvea Associated with Large Cell Carcinoma, Giant Cell Type, of the Lung

Abstract

A new syndrome consisting of bilateral diffuse malignant uveal melanoma and simultaneous occurrence of another systemic malignant neoplasm was described in 6 patients in 1982. The present study reports a seventh case. Our patient was younger than the patients previously reported. He had large cell carcinoma of the right lung. The bilateral intraocular neoplasm was characterized as a diffuse malignant uveal melanoma of the mixed cell type by light microscopy and by transmission electron microscopy. All parts of the tumor contained S-100 protein. In addition to the two primary neoplasms, the patient had a combination of Ota's and Ito's naevi on the left side.
