title: A new rosette in retinoblastoma.
abstract: Retinoblastoma, the most common primary malignant intraocular tumor of childhood is a great success story in pediatric and ocular oncology. Pathology of retinoblastoma is important to guide the treatment modalities. Differentiated retinoblastoma is commonly seen in younger age group. Since a hundred years, we have been observing two typical true rosettes in retinoblastoma in the form of Flexner-Wintersteiner (FW) and Homer Wright (HW) rosettes and in many occasions pseudorosettes have been documented. In the present case report, a third new type of rosette was identified in a differentiated retinoblastoma which had an unusual anterior segment involvement.
