title: [Late presentation of bilateral retinoblastoma: case report].
abstract: A case of retinoblastoma with uncommon features is reported, aiming at improving follow-up. In 1993, SJMMF, 9-month-old white boy, presented a squint in the left eye. A retinal tumor was detected. The patient had a family history of retinoblastoma. Enucleation was performed and retinoblastoma was proved. The patient underwent examination for staging, all were normal. The fellow eye remained normal for 10 years. During routine examination the retina map revealed three retinoblastoma white lesions in the nasal retina. The patient underwent transpupillary thermotherapy with diode laser. After 30 days, the lesions became atrophic. After 60 days there was tumor recurrence on the border of the lesion. Sclera cryotherapy was performed. There was tumor regression for six months. During follow-up, condensations next to the atrophic tumor lesions were discovered, which were vitreous seeds. Brachitherapy with 125 iodine was done. The lesions disappeared after 30 days. New vitreous seeds appeared 3 months later, set on the retina surface. They were blocked with sclera cryotherapy and transpupillary thermotherapy. The patient presented with new vitreous seeds after six months, which adhered to the retina. They were blocked with transpupillary thermotherapy. Follow-up was for 38 months since the appearance of the bilateral tumor. The patient presents normal visual acuity and clinical examination. This case is important considering the low frequency of the disease at this age. It is essential to maintain alertness when cases of retinoblastoma are seen as cured.
