Bilateral malignant melanoma of the choroid in the United States.

We examined a 73-year-old woman with bilateral malignant melanoma of the choroid associated with multiple nonocular malignancies. Fine-needle aspiration biopsy was performed in the left eye to provide a tissue diagnosis. Cytologic examination of the lesion in the left eye confirmed the diagnosis of primary malignant choroidal melanoma. This case demonstrates that bilateral malignant melanoma of the choroid occurs more frequently than expected, and may be associated with nonocular malignancies.
