腹壁外韧带状纤维瘤,又称侵袭性纤维瘤病,曾认为多发生于妇女的腹壁部位。实际上本瘤发生腹壁以外部位并非少见,因其生长较快,术后容易复发,临床上常误诊为恶性肿瘤,病理学上有时不易与纤维肉瘤鉴别。鉴于此,本文就19例腹壁外韧带状纤维瘤的临床及病理特点进行分析,重点讨论肿瘤与复发的关系。 The extra-abdominal ligamentous fibromatosis, also known as aggressive fibromatosis, was thought to have occurred in the abdominal wall of women. In fact, it is not uncommon for this tumor to occur outside the abdominal wall. Because of its rapid growth and easy postoperative recurrence, it is often misdiagnosed as a malignant tumor in clinical practice. Pathologically, it is not always easy to distinguish it from fibrosarcoma. In view of this, this article analyzes the clinical and pathological features of 19 cases of external abdominal ligamentous fibroids, focusing on the relationship between tumor and recurrence.
