ABSTRACT

<p><b>OBJECTIVE</b>To explore the diagnosis and treatment of xanthogranulomatous prostatitis.</p><p><b>METHODS</b>A 75-year-old man presented with a 3-month history of difficult urination and frequent micturition, which was exacerbated for 2 days. Digital rectal examination indicated an enlarged prostate size of II degrees with hard texture but no tenderness. Serum total PSA was 172.5 microg/L. TRUS revealed 200 ml of post-micturition residual urine, thickened bladder wall, prostate size of 4.3 cm x 3.8 cm x 5.0 cm and no isochrones. MRI showed an enlarged prostate gland, with marked enlargement of the central zones and low-signal intensity of the peripheral gland, part of the prostate gland protruding to the bladder with no clear dividing line. It was diagnosed as prostate cancer initially, and confirmed by needle biopsy.</p><p><b>RESULTS</b>Histopathological examination revealed large numbers of "foamy macrophages" in the lesion, with a few multinucleated giant cells, leukocytes, mononuclear, plasmocytes and fibroplasia. Immunohistochemistry showed CD68 (+) and PSA (-). The patient was treated with oral Tamsulosin and glucocorticoid and by temporary catheterization, and followed up for 20 months. Urination symptoms began to alleviate and serum PSA to decrease at 4 months. The PSA level was 9.2 microg/L at 13 months and 3.6 microg/L at 17 months.</p><p><b>CONCLUSION</b>Xanthogranulomatous prostatitis is a rare clinically, which can be confirmed by histopathological examination. It is treated mainly by supportive therapy and, for the cases with severe lower urinary tract obstruction, TURP can be employed. Follow-up must be performed by possible examination of PSA and necessary needle biopsy of the prostate.</p>
