Two Cases of Primitive Neuroectodermal Tumors in Infancy

ABSTRACT

The authors are reporting two cases of huge primitive neuroectodermal tumors involving cerebral hemisphere. These are highly malignant neoplasm, both clinically and histologically. They are rapidly growing tumors, with a brief duration of symptoms and a rapidly progressive course. The patients were discharged after subtotal resecton of tumor mass with an uneventful course, but one was dead within 2 months after the operation. These tumors usually occur in children and young adult. We have experienced two cases surgically treated in infancy.
