 Abstract

- A 63-year-old male patient with extensive carcinoma in situ of the urinary bladder was found to have unsuspected transitional cell carcinoma of the prostate. Mapping of the totally embedded radical cystectomy specimen demonstrated diffuse, multifocal, epithelial abnormalities, ranging from mucosal atypia to the nonpapillary carcinoma in situ with extension to the urethra, prostatic ducts and glands, seminal vesicles and ureter, probably reflecting individual urothelial susceptibility in reaction to carcinogenic stimulus. The importance of prostatic assessment in the evaluation of the patient with carcinoma in situ of the urinary bladder is emphasized.

Abstract
PDF
- We studied distribution of fibronectin in paraquat-induced adult fibrotic lung by indirect immunofluorescence and indirect immunoperoxidase methods, using affinity-purified antifibronectin IgG peroxidase conjugates and antifibronectin IgG FITC conjugates. In contrast to the relative paucity of staining in normal lung, there was a marked increase in interstitial staining for fibronectin in this fibrotic lung. This marked alterations in the apparent amounts and distribution of fibronectin in fibrotic human lung suggest its involvement in the cellular events accompanying human lung fibrosis.
