Zusammenfassung
Der vorliegende Fallbericht beschreibt einen 79-jährigen Patienten mit der seltenen Lokalisation eines gastrointestinalen Stromatumors (GIST) der vorderen Rektumwand, imponierend als Raumforderung zwischen Prostata und Rektum. Hier lag zusätzlich eine ausgeprägte subvesikale Obstruktion und PSA-Werterhöhung vor. Daher wählten wir nach histologischer Sicherung der Diagnose als operativen Zugang die simultane radikale retropubische Prostatektomie: einen unserer Ansicht nach im Vergleich zur abdominoperinealen Resektion großzügigeren und weniger traumatisierenden Operationsverfahren. Dieser Fallbericht zeigt, dass bei Raumforderungen mit Lokalisation zwischen Prostata und Rektum neben dem Vorliegen eines Prostatakarzinoms differentialdiagnostisch die seltene Tumorentität eines GIST mit in Betracht bezogen werden sollte.
Abstract
This case report deals with a 79-year-old patient with a gastrointestinal stromal tumor (GIST) of the anterior rectal wall which was unusually located between the rectum and the prostate gland. In addition, this patient suffered from subvesical obstruction accompanied by an elevated PSA level. These circumstances led to our decision to operate on the tumor via simultaneous radical retropubic prostatectomy. In our opinion this resection technique was easier and less traumatic for the patient compared to procedures performed via the abdomen and perineum. This case report demonstrates that in the case of tumors located between the rectum and the prostate gland the differential diagnosis should include not only prostate carcinoma but also rare tumor entities such as GIST.
