Transitional cell carcinoma in situ of the seminal vesicles: 8 cases with discussion of pathogenesis, and clinical and biological implications.
ABSTRACT
PURPOSE
Mucosal migration of transitional cell carcinoma in situ is a potential mechanism for multifocal lower tract disease.
MATERIALS AND METHODS
The clinical course and pathological studies of 8 cases of carcinoma in situ are reviewed in detail.
RESULTS
The pattern of disease of carcinoma in situ of seminal vesicle provides circumstantial evidence for mucosal migration of cancer from a bladder or prostatic urethral origin.
CONCLUSIONS
A monoclonal origin of bladder cancer combined with mucosal spread of carcinoma in situ suggests that incomplete destruction of carcinoma in situ may adversely affect long-term results by permitting extension into the distal ureters, prostatic duct or seminal vesicles. Protracted intravesical treatment of carcinoma in situ without complete elimination of the disease allows the natural history of mucosal spread to become evident.
Related Questions
Would radical prostatectomy and PLND suffice or would a cystectomy be warranted (even in the absence of bladder involvement) as well?

Primary urothelial carcinoma of seminal vesicle is extremely rare. There is some skepticism whether this is a true entity. More common is the secondary spread from bladder pri...
