We report a case of a 72-year-old male that underwent two sets of transrectal prostatic needle biopsy (TPNB) within 9 month period. Pathology showed unremarkable benign prostatic tissues in the first group of biopsies while extensive diffuse inflammation with the characteristic features of malakoplakia in the second set. Three cores in the repeat biopsy contained foci of prostatic adenocarcinoma as well. Occurrence of malakoplakia several months after TPNB in our case suggests that microorganisms may have been inoculated to the prostate during the biopsy procedure. We believe that malakoplakia must be added to the list of complications after TPNB.
我们报告一例72岁男性患者，在9个月内接受了两组经直肠前列腺穿刺活检（TPNB）。病理显示第一组活检的前列腺组织为良性，无异常，而第二组活检显示广泛弥漫性炎症，并具有软斑病的特征性表现。再次活检的三个组织芯中也含有前列腺腺癌灶。在我们的病例中，TPNB数月后出现软斑病，提示在活检过程中可能已将微生物接种到前列腺。我们认为软斑病应被列入TPNB后的并发症清单。
