title: Primary Pulmonary Primitive Neuro-Ectodermal Tumour (PNET) in an Eight-Year-Old Girl - A Rare Case.
abstract: Primitive Neuro-Ectodermal-Tumours (PNET) and Ewing's sarcoma are part of the spectrum of Ewing's Family of Tumours (EFT) and show varying degrees of neuroectodermal differentiation. Both these tumours share similar histological and genetic features. PNETs arising primarily in the lungs without pleural or chest wall involvement are extremely rare. We report a case of pulmonary PNET in an eight-year-old girl. To the best of our knowledge, this is the youngest case of primary pulmonary PNET to be reported in paediatric age group in the Indian literature.
