[Pleuropulmonary blastoma in an adult women with pleurorrhea as the major clinical manifestation: report of a case].
Pleuropulmonary blastoma (PPB) is a rare dysontogenetic neoplasm in children and has been recognized as a distinct clinicopathological entity different from the ordinary pulmonary blastoma of adulthood. We report a very rare adult case of PPB. A 43-year-old female patient presented with massive pleural infusion, and a misdiagnosis of pleural tuberculosis (TB) was made on the basis of ultrasound scan and CT images, for which therapy with TB drugs was administered for 3 weeks. Subsequent operation and pathologic examination of the mass revealed a multicystic neoplasm consisting of malignant mesenchymal cells immunohistochemically positive for vimentin and actin. Local recurrence occurred in the left pleural 20 months after the surgical tumor resection and 4 cycles of adjuvant chemotherapy.
