Metastatic ciliary body carcinoid tumor.

A 50-year-old man with a history of systemic carcinoid had decreased right eye vision and a darkly pigmented cilio-choroidal mass. Results of ultrasonographic and fluorescein angiographic examinations were consistent with a malignant melanoma. Fine-needle aspiration biopsy of the lesion identified it as a carcinoid metastasis. The patient refused both radiation and enucleation; complete excision with a cyclochoroidectomy was performed. Histopathologic examination showed a carcinoid neoplasm covered by marked hyperplasia of the retinal pigment epithelium that produced the pigmented appearance of the lesion.
