title: Metastatic carcinoid tumor in the orbit.
abstract: In 1991, a carcinoid tumor of the duodenum with metastasis in the regional lymph nodes was resected in a 39-year-old-man. A metastasis in the mediastinum was found and was resected in 1996. In 1999, a metastasis in the left lung was discovered and was excised. In 2001, he noticed right-sided diplopia, and a computed tomography (CT) scan disclosed a tumor of 2 cm diameter in the right orbit with infiltration to the frontal sinus. The tumor was resected, and was diagnosed metastatic carcinoid tumor. An orbital metastasis of carcinoid tumor is rare, and only about 30 cases have been reported in the English literature. The rarity metastasis of carcinoid tumors in the orbit prompted us to report this case.
