Xanthogranulomatous prostatitis with prostato-rectal fistula: a case report and review of the literature.
OBJECTIVE
Xanthogranulomatous prostatitis (XP) is a rare form of nonspecific granulomatous prostatitis that can clinically mimic high-grade prostatic carcinoma. It is difficult to diagnose it definitely in clinical settings.


METHODS
We report a case of XP with prostate-rectal fistula and review the relevant literatures.


RESULTS
A 75-year-old man presented with rectal bleeding when he urinated. A locally advanced carcinoma of prostate was suspected initially following the physical, imaging, and hematologic examinations. Subsequently on histopathological and immunohistochemical staining after needle biopsy of the prostate, a diagnosis of XP was made definitely. The patient was catheterized temporarily and treated with tamsulosin and estrogen. The patient underwent uneventful recovery after this conservative therapy.


CONCLUSIONS
Histologic and immunohistochemical analyses are valuable in differentially diagnosing XP from high-grade prostate carcinoma. Treatment strategy of XP in principle is recommended to be the conservative method. Long-term follow-up earns are highly regarded considering the possibility of coexisting prostate cancer.
