A case of a solitary fibrous tumor (SFT) of the pelvic space in a 64-year-old man is reported herein. Computed tomography (CT) of the pelvis showed a large mass enhanced heterogeneously left paracentral and posterior to the bladder and intimately associated with prostate. The site of origin of the mass could not be defined on CT because margins blended with the bladder, prostate, and rectum. A tumorectomy was performed and has remained well with no evidence of recurrence during the last 3 months. The tumor was 12.5 x 9.5 x 8.3 cm in size, solid with a fibromuscular capsule, and gray-tan in color. Histologically, the neoplasms were well circumscribed and composed of short spindle cells arranged without an obvious pattern. Immunohistochemically, these cells were strongly positive for CD 34 and negative for S-100, alpha SMA, and AE1/AE3.
本文报道了一例64岁男性盆腔孤立性纤维瘤（SFT）病例。骨盆计算机断层扫描（CT）显示膀胱左中央后方有一个大肿块，不均匀强化，且与前列腺紧密相连。CT上无法确定肿块的起源部位，因为其边缘与膀胱、前列腺和直肠融合。进行了肿瘤切除术，在过去3个月中患者恢复良好，无复发迹象。肿瘤大小为12.5×9.5×8.3cm，质地坚实，有纤维肌性包膜，呈灰棕色。组织学上，肿瘤边界清晰，由短梭形细胞组成，排列无明显模式。免疫组化显示，这些细胞CD 34呈强阳性，S-100、α-SMA和AE1/AE3呈阴性。
