• Bilateral orbital masses developed in a 65-year-old woman with known ileal carcinoid tumor. Biopsy of the left orbital mass revealed metastatic carcinoid tumor. Surgical manipulation of the tumor resulted in a marked, reproducible rise in systemic blood pressure (BP). A marked rise in systemic BP on palpation of an orbital tumor should lead one to suspect metastatic carcinoid tumor.
