RESUMEN
A 62-year-old man with anal pain was diagnosed with rectal neuroendocrine carcinoma. There were multiple metastases in the liver, lung, paraaortic lymph node, and bone of the patient. After performing a diverting colostomy, irinotecan and cisplatin were administered. Partial response was obtained after 2 courses, and anal pain improved. However, after 8 courses, multiple skin metastases were found on his back. At the same time, the patient also complained of redness, pain, and impaired vision in the right eye. Iris metastasis was diagnosed clinically by ophthalmologic examination and with contrast- enhanced MRI. Iris metastasis was treated with 5 doses of 4 Gy irradiation, ameliorating the eye symptoms. The patient died of the original disease 13 months after the initial diagnosis; however, multidisciplinary treatment appeared effective for palliating cancer symptoms.
