Abstract

Introduction

Inflammatory myofibroblastic tumors are difficult to diagnose because of the lack of specific indicators. We describe a diagnostically challenging case of an inflammatory myofibroblastic tumor primary to the peritoneum.

Case presentation

The patient was a 25-year-old male who presented at our hospital with lower abdominal pain. Computed tomography revealed a mass lesion 80 mm in diameter just above the bladder. This was suspected to be a bleeding tumor of the urachus. Since malignancy could not be ruled out, surgery was planned. This revealed a fragile tumor arising from the peritoneum. Following its removal, the tumor was diagnosed by histopathological analysis as an inflammatory myofibroblastic tumor.

Conclusion

We describe a case of inflammatory myofibroblastic tumor primary to the peritoneum diagnosed by histopathology. Inflammatory myofibroblastic tumor should be considered in the differential diagnosis of abdominal wall and anterior bladder tumors.

腹膜原发性炎性肌纤维母细胞瘤的诊断难题病例

由于缺乏特异性指标，炎性肌纤维母细胞瘤很难诊断。我们描述了一例原发于腹膜的炎性肌纤维母细胞瘤，诊断难度很大。患者是一名25岁的男性，因下腹疼痛来我院就诊。计算机断层扫描显示，膀胱上方有一个直径 80 毫米的肿块。怀疑是尿道出血性肿瘤。由于无法排除恶性肿瘤的可能性，因此计划进行手术。手术发现了一个来自腹膜的脆弱肿瘤。我们描述了一例通过组织病理学诊断的原发于腹膜的炎性肌纤维瘤。炎性肌纤维母细胞瘤应在腹壁和膀胱前部肿瘤的鉴别诊断中予以考虑。
