探讨侵袭性纤维瘤病的临床表现、影像学特征和治疗方法及预后，以提高对该病的认识并为该病的临床诊治提供参考。

报道1例术前被误诊为腹壁子宫内膜异位症的腹壁侵袭性纤维瘤患者的诊疗过程，并复习相关文献。

手术切除肿块及肿块周围组织，并予补片修补缺损组织，术后病理提示梭形细胞病变，结合免疫组化符合侵袭性纤维瘤病，未行后续治疗，随访3月未见复发。

侵袭性纤维瘤病为发病机制不明确的交界性肿瘤，具有复发率高、局部侵袭性强等特点，由于其发病率较低，目前尚无针对该病的诊疗规范，无症状患者可观察等待，其余患者可选择以手术为主的综合治疗。

To explore the clinical manifestations, imaging characteristics, minimally invasive surgical treatment, and prognosis of aggressive fibromatosis (AF), aiming to enhance the understanding of the disease and provide a reference for its clinical diagnosis and management.

A case initially diagnosed preoperatively as abdominal wall endometriosis following cesarean section was reported. The patient underwent single-port laparoscopic resection, and postoperative pathology confirmed a diagnosis of abdominal wall AF. A literature review was conducted to support the discussion.

The mass and surrounding tissue were excised via single-port laparoscopy, and a mesh was used to repair the resulting tissue defect. Postoperative pathology revealed a spindle cell lesion, and immunohistochemical analysis confirmed the diagnosis of AF. No adjuvant therapy was administered, and no recurrence was observed during a 3-month follow-up period.

Aggressive fibromatosis is a borderline tumor with an unclear pathogenesis, characterized by high recurrence rates and strong local invasiveness. Due to its low incidence, there are currently no standardized diagnostic or treatment protocols. While open surgical resection remains the primary treatment approach, this case demonstrated that single-port laparoscopic resection can also achieve satisfactory therapeutic outcomes.
