A retinoblastoma occurring in an adult always evokes interest. These tumors are most common before the age of three and rarely occur after the age of ten.1 In 1929 Verhoeff2 reported a retinoblastoma in a man 48 years old. Rasmussen3 in 1944 reported another case in a man of 48, and at that time he reviewed the literature for adult cases. In Wintersteiner's series of 429 cases of retinoblastoma the oldest patient was 16 years. Magbe reported a case in a 20-year-old woman; Gerard and Detray in a 66-year-old woman and Gerard and Morel in a 35-year-old man. These last two cases were questioned by Verhoeff who thought they were instances of massive gliosis. More recently cases were reported in a 53-year-old4 and in a 45-year-old man.5 No mention of survival time after enucleation was made in any of these reports. This case report
