Inflammatory pseudotumors, also known as inflammatory myofibroblastic tumors, are uncommon benign tumors of unknown etiology which may develop at several anatomical sites. In the urogenital tract, inflammatory pseudotumor usually affects the urinary bladder or the prostate. Inflammatory pseudotumor of the kidney is very rare. It is considered as a reactive inflammatory lesion that features very good prognosis.
We present the case of a 57-year-old Moroccan man who presented with a two-month history of gross hematuria and left lumbar pain. Imaging investigations revealed a left kidney mass and pathological examination of the nephrectomy specimen showed an inflammatory pseudotumor.
As the preoperative definitive diagnosis of such a tumor is not possible, surgery is advised because only pathological examination of the nephrectomy specimen can establish the diagnosis with certainty. From one case report and literature review, the authors suggest a diagnostic and therapeutic strategy for the management of this rare tumor.
炎性假瘤，也称为炎性肌纤维母细胞瘤，是病因不明的罕见良性肿瘤，可发生于多个解剖部位。在泌尿生殖道中，炎性假瘤通常累及膀胱或前列腺。肾脏炎性假瘤非常罕见。它被认为是一种反应性炎性病变，预后非常好。
我们报告一例57岁摩洛哥男性，有两个月肉眼血尿和左腰痛病史。影像学检查发现左肾肿块，肾切除标本的病理检查显示为炎性假瘤。
由于术前无法对此类肿瘤做出明确诊断，建议进行手术，因为只有肾切除标本的病理检查才能确定诊断。通过一例病例报告和文献综述，作者提出了针对这种罕见肿瘤的诊断和治疗策略。
