Zusammenfassung
Die Standardmethode zur histologischen Verifizierung eines Prostatakarzinoms ist die ultraschallgesteuerte transrektale Prostatastanzbiopsie. Aus Einzellfallberichten ist eine lokale Tumorzellaussaat nach Stanzbiopsien bekannt.
Es wird der Fall eines 64-jährigen Patienten beschrieben, bei dem sich 2 Jahre nach radikaler Prostatovesikulektomie wegen Prostatakarzinom als Zufallsbefund im Rahmen einer Proktokolektomie bei Pancolitis ulcerosa eine Mikrometastase des Prostatakarzinoms in der Lamina submucosa des distalen Rektums fand. Als mögliche Ursache dieser Metastase kommt eine Implantationsmetastase im Rahmen der präoperativ erfolgten transrektalen Prostatastanzbiopsie differentialdiagnostisch in Betracht.
Abstract
Transrectal ultrasound-guided prostate biopsy is the standard technique to detect prostate cancer histologically. Based on a few case reports, it is known that prostate biopsy can cause a seeding of tumor cells.
We report the case of a 64-year-old man who 2 years after radical prostatectomy for prostate cancer underwent proctocolectomy because of ulcerative pancolitis. In the lamina submucosa of the distal rectum a micrometastasis of the prostate cancer was found. A possible reason for this metastasis is an implantation of prostate cancer cells due to the transrectal biopsy of the prostate.
