چکیده
and destruction of bone, usually the adjacent vertebrae and ribs posteriorly. There is a striking absence of intrathoracic metastasis, as shown by roentgenologic studies. No post-mortem studies were made in his series of seven cases. In two cases biopsy specimens showed carcinoma. One is recorded as carcinoma spinocellulare and in the other the type is not given. Pancoast calls these cancers “superior pulmonary sulcus tumors,” and suggests that they arise from an ernbryonic remnant of the fifth branchial pouch. We have studied three cases which seem to belong in this grqup ttnd from our observations believe that the tumors originated in the lung and that they are a clinically distinct and generally unrecognized type of cancer. Two cases were studied at autopsy; in the other biopsy was done.

Unlike the primary tracheal tumors, squamous cell carcinoma of trachea is common, especially in smokers. This type of tumor has a low rate of survival and it is diagnosed too late on account of late presentation of its signs. The treatment of choice is surgical removal followed by adjuvant radiotherapy; Primary radiotherapy is the appropriate treatment in inoperable cases. In this study, we pre...

Adenocarcinomas are the most common cause of malignancy in pleura fluids. Usual primary sites include the lung, breast, gastrointestinal tract, and genitourinary tracts. Predicting the site of origin of an adenocarcinoma can be difficult due to overlapping morphologic characteristics. We investigated the use of alkaline phosphatase (AP), Cytokeratin7 (CK7) Cytokeratin8 (CK8) to distinguish aden...

We present the case of a 40 years old female presenting with a solitary apical lung mass, associated Horneŕ syndrome and evidence of medullary compression. Although she had a history of cervical cancer, a primary lung tumor was suspected. Tissue biopsy confirmed cervical cancer metastasis, highlighting the fact that although metastasis usually presents as multiple lung nodules, solitary lesions...
