Keywords:Primitive neuroectodermal tumour (PNET), Mediastinal tumour, Horners syndrome, Superior vena caval onbstruction, Round cell tumour, CD 99
Primitive neuroectodermal tumour (PNET) is a rare mediastinal tumour which may infiltrate pulmonary parenchyma and chest wall. Histopathologically, it is a round cell tumour, and on immunohistochemistry, tumour cells express for CD – 99 (MIC – 2). Here we report a rare case of PNET presented as unresectable mediastinal tumour with chest wall infiltration, superior vena caval obstruction and Horner’s syndrome in an adolescent female.
