title: Uncommon pleural effusion: pleuropulmonary metastasis from primitive neuroectodermal tumor.
abstract: Primitive neuroectodermal tumor is an invasive neoplasm with neuronal differentiation, which frequently results in metastasis in various organs. We report the case of a patient with primitive neuroectodermal tumor whose primary site was the axilla. The patient presented with metastases in the lung, pleura, bone, iliac muscle and bone marrow. We highlight the uncommon finding in the pleural fluid cytology.
