Retinoblastoma in an adult.
BACKGROUND
Retinoblastoma is the most common pediatric ocular tumour. It may rarely present in adults. The present case adds to the number of 26 cases already published in literature since 1919 till 2013. Our aim is to highlight the rare occurrence of retinoblastoma in adults along with its features which differentiate it from paediatric retinoblastoma.


METHODS
We describe a case of adult onset retinoblastoma (group E, according to the international classification of retinoblastoma) occurring in a 25 year old male. He presented with decreasing visual acuity in the right eye of 4 months duration. He had neo-vascular glaucoma and pseudohypopyon. B scan ultrsonography of his right eye showed intraocular growth without any calcification. The CT scan of the orbits and brain showed intraocular growth in the right eye with no calcification. Enucleation of the right eye was carried out. Retinoblastoma was confirmed on histopathology of the enuleated globe.


CONCLUSIONS
The present case adds to the number of adult Rb patients reported in literature. Early detection to salvage the life can be made possible if the clinician keeps a high index of suspicion when observing retinal mass of adult onset. Proper counselling of the patient in order to seek his full involvement in management may help in improving the prognosis of the disease.
