In tissue sections, thyroid transcription factor-1 (TTF-1) is a sensitive marker for adenocarcinomas of lung and thyroid origin. This immunohistochemical study evaluates the effectiveness of TTF-1 as a marker for pulmonary adenocarcinomas in paraffin sections of cell block preparations derived from effusion and fine-needle aspiration specimens. We evaluated 122 cell blocks including 8 primary a...

Background: Little is known about the correlation between nodal upstaging and pulmonary nodules classified according to presence of solid components in lung mediastinal windows. This study thus aimed analyze risk factors prognosis based on different imaging features, clinical characteristics, pathological results from patients with stage T1N0M0 adenocarcinoma.

The lung is the most common site for metastasis from colorectal cancer, which is among the most common neoplasms in developed countries. Simultaneous occurrence of pulmonary metastasis of colorectal origin and primary carcinoma has been reported. We describe the case of a 65-year-old man who underwent low anterior resection for colorectal adenocarcinoma in 2007. Follow-up computed tomography re...
