In an attempt to better understand the biologic behavior of neoplastic cell metastasis, a histochemical study with the use of six different lectins and a monoclonal antibody against human pulmonary surfactant apoprotein (PE-10) was carried out on primary adenocarcinomas of the lungs and their regional (usually lymphatic to lymph nodes or contralateral lung) and distant (usually hematogenous to extrathoracic organs) metastatic lesions of 54 postmortem cases. Primary pulmonary adenocarcinomas were classified further into acinar, papillary, and solid types according to WHO histological typing. Acinar type primary adenocarcinoma of the lungs showed significantly higher (p less than 0.05) binding reactions to Ricinus communis-I (RCA-I) and Ulex europaeus-I (UEA-I) lectins than solid type adenocarcinoma. With six different lectins, concordantly positive reactions between primary pulmonary adenocarcinomas and their lymphatic and hematogenous metastases were seen in 67% or more cases, and with soybean agglutinin (SBA) and UEA-I the concordance rates between primary and lymphatic metastases (lymph nodes and contralateral lungs, respectively) were significantly higher (p less than 0.05) than those between primary and hematogenous metastases. With PE-10 immunohistochemistry, concordantly positive reactions between primary and metastases were low, especially in cases of distant hematogenous metastases (25%), but the statistical significance of differences was missed by narrow margins. With alcian blue PAS-stain, concordantly positive reactions of mucin production between primary adenocarcinomas and both lymphatic and hematogenous metastases were high (92%), but there was no evidence of correlation between lectin bindings and alcian blue-PAS reactions to either primary or metastatic lesions of pulmonary adenocarcinomas.

Metastases to the larynx from distant primaries are very rare. The present article reports a case of metastatic papillary adenocarcinoma of the larynx of lung origin. The patient was a 59-year-old female non-smoker, who had a history of adenocarcinoma of the right lung. For the laryngeal tumor, we performed a partial laryngectomy following biopsy. The tumor of the larynx was a papillary adenocarcinoma resembling the lung tumor, both demonstrating positive immunohistochemical staining for pulmonary surfactant apoprotein. The findings emphatically indicated the laryngeal tumor to be metastasis from the primary papillary adenocarcinoma of the lung. The present case report presents the clinical findings, course of disease and histopathological findings with brief reviews of the literature.

We report a case of primary pulmonary adenocarcinoma which metastasized to the uterine cervix. A 69-year-old postmenopausal Japanese female was admitted to our hospital because of general fatigue and atypical genital bleeding. Four years before, she had undergone video-assisted thoracoscopic right upper lobectomy, for primary lung cancer (adenocarcinoma), stage IIIb, pT3N1M0. Gynecologic investigation showed a cauliflower-like tumor in the uterine cervix and parametrial invasion towards the bilateral pelvic wall. Metastasis of extragenital carcinoma to the cervix uteri is rare. Most such reported cases originated in the breast and gastrointestinal tract. In this case, cervical biopsy specimens were revealed to be adenocarcinomatous, similar in pathological features to the previously resected lung cancer. Immunohistochemical staining was positive for thyroid transcription factor-1 and pulmonary surfactant apoprotein A and negative for CA125 and thyroglobulin. Although rare, the respiratory tract should be considered as a possible primary site of uterine cervical metastatic carcinoma.
