Abstract

AA is a 45-year-old man with a history of flushing and diarrhea complained of distortion of vision in his left eye. Examination showed an orange-tinted tumor just temporal to the macula. Echography showed a dome-shaped lesion on B-scan, and A-scan showed low-to-medium internal reflectivity with some irregularity and mild spontaneous vascularity (Fig. 1). It was suspicious for a melanoma, but the irregularity was atypical. Systemic workup included a chest CT scan which found a mass in the left lower lobe of the lung. A 24-h urine test for metabolites of serotonin was performed and was positive for 5-HIAA. The diagnosis of a carcinoid tumor of the lung with choroidal metastasis was made. This lesion is relatively rare cause of choroidal metastasis. Patients with metastatic carcinoid have a relatively long survival rate compared to other metastatic malignancies [63].
