Choriocarcinoma metastatic to the lung. A cytologic study with identification of human choriogonadotropin with an immunoperoxidase technique.

A case of choriocarcinoma metastatic to the lung following a previous hydatidiform mole is presented. It was possible to make definitive identification of trophoblastic elements on a needle aspiration biopsy using an immunoperoxidase staining technique, thus avoiding diagnostic thoracotomy prior to therapeutic intervention. A method of immunoperoxidase staining of previously fixed and Papanicolaou-stained needle aspiration biopsy specimens is also described, and other uses of the immunoperoxidase technique on needle biopsy specimens are discussed.

Giant-cell carcinoma of the lung. A cytologic study.

A case of giant-cell carcinoma of the lung, confirmed at autopsy, is presented. The cytologic features seen in sputum samples, bronchial washings and brushings and fine needle aspiration biopsy material as well as the histologic findings are described. The possible relationship to bronchioloalveolar carcinoma is discussed. The cytologic features of giant-cell carcinoma of the lung, when seen in the context of the clinical and radiologic setting, should allow the cytologic identification of the tumor prior to surgical intervention.
