Pleuropulmonary blastoma: diagnosis by fine-needle aspiration cytology: a case report.
Pleuropulmonary blastoma (PPB) is an unusual pleural-based blastoma presenting in childhood composed by undifferentiated sarcomatous tissue with divergent differentiation and occasional benign epithelial-lined structures. We are presenting the cytologic features of PPB as diagnosed by fine-needle aspiration cytology (FNAC) of the lower lobe of the right lung in a 4-year-old girl. The smears showed highly malignant cells with hyperchromatic oval or multilobulated pleomorphic nuclei strongly suggesting an aggressive sarcoma. Histology of the aspirated material also revealed small fragments of a myxoid sarcoma with some pleomorphic anaplastic cells. Lobectomy and surgical pathologic investigation confirmed the diagnosis. PPB seems to be another tumor in which accurate diagnosis may be achieved by FNAC.
