Abstract

Introduction

Xanthogranulomatous prostatitis is a very rare benign inflammatory lesion of the prostate that may be similar to prostatic carcinoma in clinical presentation and radiological characteristics.

Case presentation

A 77-year-old man was admitted to our hospital because of high prostate-specific antigen level. Magnetic resonance imaging showed a 6.5 cm in diameter multifocal mass with hemorrhage at the base of the left lobe of the prostate. Biopsy was performed. Histopathological examination revealed no evidence of malignancy. After biopsy, he developed recurring fever, so the patient was treated with open suprapubic tumor resection to control infection. Pathological examination revealed xanthogranulomatous prostatitis.

Conclusion

It is necessary to diagnose xanthogranulomatous prostatitis by cooperation between urologists and pathologists, and consider xanthogranulomatous prostatitis as a differential diagnosis. Treatment should be conservative in principle; however, surgical intervention may be necessary.

核磁共振成像显示黄粒肉芽肿性前列腺炎伴多发性肿块。

简介：黄原细胞瘤性前列腺炎是一种非常罕见的前列腺良性炎症病变，临床表现与前列腺癌相似：黄疽性前列腺炎是一种非常罕见的前列腺良性炎症病变，其临床表现和影像学特征可能与前列腺癌相似：一名 77 岁的男性因前列腺特异性抗原水平过高而入住我院。磁共振成像显示，前列腺左叶底部有一个直径为 6.5 厘米的多灶性肿块，并伴有出血。进行了活组织检查。组织病理学检查未发现恶性证据。活组织检查后，患者出现反复发热，因此采用开放性耻骨上肿瘤切除术治疗，以控制感染。病理检查显示为黄疽性前列腺炎：结论：有必要通过泌尿科医生和病理学家的合作来诊断黄疽性前列腺炎，并将黄疽性前列腺炎作为鉴别诊断。治疗原则上应采取保守疗法，但也可能需要手术干预。
