Non-prostatic pathology on prostate needle-biopsy - colorectal carcinoid: a case report.
BACKGROUND
Prostate needle-biopsies are among the most common specimens in routine histopathological practice; in 15% colorectal tissue is also present. Rectal pathology is described to be found in 17% of this coincidentally obtained material.


METHODS
We present a case in which colorectal carcinoid was found in the rectal mucosa obtained via transrectal prostate biopsies in a screening program for prostate cancer in a 71-year old Caucasian male. To the best of our knowledge, this was the first time that such a coincidental finding was discovered. Besides a colonoscopy with polypectomy, this coincidental detection remained without any further clinical consequences for this patient until today.


CONCLUSIONS
As there is a considerable chance that abnormalities are found in the rectal tissue of prostate biopsies, it is advisable for all pathologists to include this tissue in the histology evaluation and look for potential irregularities in this simultaneously collected material.
