RESUMO
Primitive neuroectodermal tumor (PNET) is a small round cell malignant tumor of neuroectodermal origin. Most of the PNETs occur in the central nervous system (CNS). PNETs recognized outside of CNS are diagnosed as peripheral PNET (pPNET). This tumor which expresses MIC-2 gene (CD99) seems to be least aggressive after complete tumor resection. We describe a rare case of PNET in a young girl.

We conducted an institutional-based retrospective study on 308 uveitic patients and analyzed the pattern of uveitis in Northeastern India. Anterior uveitis was the most common type (47.07%) followed by posterior (29.87%), intermediate (12.98%) and panuveitis (10.06%). Toxoplasmosis (40.21%) had the highest incidence among posterior uveitis cases. Harada's form of Vogt Koyanagi Harada's disease is a frequent occurrence in this subset of the population.
