罕見背痛原因：後腹膜腔軟化症－－個案報告

A Rare Etiology of Back Pain: A Case Report of Retroperitoneal Malakoplakia

後腹膜腔的軟化斑是相關文獻報導中罕見的發炎性肉芽腫病變。一名59歲患有糖尿病的女性主述有長達一個月的背痛，腹部電腦斷層掃描顯示位於肝臟下方和右腎之間的位置有腫塊，因此使用經驗性抗生素來治療高燒狀況，同時以外科手術摘除後腹膜腔的腫塊。病理學呈現出具有軟化斑獨有特徵的Michaelis-Gutmann bodies，經過3年的追蹤治療，並沒有任何軟化斑復發的跡象。我們也回顧近年與軟化斑病人已發表有關研究文獻的綜述加以分析與比較。

Retroperitoneal malacoplakia is an inflammatory granulomatous disease rarely reported in the literature. A 59-year-old woman with diabetes mellitus came into our clinic complaining of back pain that had lasted about one month. Computed tomography scan of the abdomen revealed a loculated low-attenuation septated mass located between the inferior liver and right kidney. Because she had a high fever, antibiotics were administered empirically. During perisurgical intervention, she was found to have one retroperitoneal mass. Pathologic findings of the tumor revealed malacoplakia with distinctive Michaelis-Gutmann bodies. At three years of follow-up, the patient was found to have had no recurrence of malacoplakia. Herein we review her and review of published studies on patients treated for malacoplakia.
