title: Primitive neuroectodermal tumour of the maxilla. Light microscopy and ultrastructural observations.
abstract: Primitive neuroectodermal tumour is a rarely encountered lesion, mainly occurring within the central nervous system. A case is reported in which the tumour was situated in the anterior maxilla. Light microscopy and ultrastructural features that made it possible to differentiate the lesion from other small round-cell tumours are discussed. Combined surgical and radiotherapeutic intervention proved to be successful in eradicating the neoplasm.
