Simultaneous expression of c-erbB-1, c-erbB-2, c-erbB-3 and c-erbB-4 receptors in non-small-cell lung carcinomas: correlation with clinical outcome.

The expression of c-erbB receptors was immunohistochemically examined in paraffin embedded specimens from non-small-cell lung carcinomas. A total of 209 patients were enrolled [squamous-cell carcinomas (n=59), adenocarcinomas (n=130), large-cell carcinomas (n=15) and giant-cell carcinomas (n=5)]. The HercepTest kit scoring guidelines were used for the interpretation of positivity.

Active remodeling in idiopathic interstitial pneumonias: evaluation of collagen types XII and XIV.

Fibril-associated collagens with interrupted triple helices (FACITs) XII and XIV act as fibril organizers and assist in the maintenance of uniform fibril size. We investigated the spatial expression patterns of collagens XII and XIV in cryptogenic organizing pneumonia (COP)/organizing pneumonia (OP) and in idiopathic pulmonary fibrosis (IPF)/usual interstitial pneumonia (UIP) and compared them to normal human lung. Study subjects included 10 patients with COP/OP, 10 patients with IPF/UIP, and 8 control subjects.

A novel combination of multiple primary carcinomas: urinary bladder transitional cell carcinoma, prostate adenocarcinoma and small cell lung carcinoma--report of a case and review of the literature.

Background: The incidence of multiple primary malignant neoplasms increases with age and they are encountered more frequently nowadays than before, the phenomenon is still considered to be rare.

Case Presentation: We report a case of a man in whom urinary bladder transitional cell carcinoma, metachronous prostate adenocarcinoma and small cell lung carcinoma were diagnosed within an eighteen-month period. The only known predisposing factor was that he was heavy smoker (90-100 packets per year).
