Recently, the Department of Hernia and Abdominal Wall Surgery at Huashan Hospital, Fudan University, has treated a number of PMS patients complaining of abdominal wall masses, which has attracted our extra attention! These patients had a few things in common: 1) they were all very young, between 25-40 years old; 2) they were all PMSCs; and 3) some of them had already undergone surgical treatment at an outside hospital, and were referred to us after they had a recurrence shortly after surgery. Their disease was called abdominal wall sclerofibroma, also known as ligament-like fibroma of the abdominal wall. Although this disease is a benign tumor, it has the manifestation of malignant tumor such as invasiveness, so it is also called junctional tumor. Surgery without attention and extended resection can easily cause local recurrence. Of course, endometriosis at the incision after cesarean section and some benign tumors originated from the subcutaneous tissue of the abdominal wall, such as lipoma, etc., also need to pay attention to. Surgical treatment for abdominal wall sclerofibromas must be based on several principles. Firstly, surgical operation must be performed according to the principle of tumor-free to avoid recurrence of medical implantation to the greatest extent; secondly, rapid frozen pathology must be sent to clarify the diagnosis during the operation, and if it is abdominal wall sclerofibroblastic tumor, then continue to expand the resection, and the resection range should be at least more than 3cm around the tumor, and frozen pathology should be sent to ensure that the margins of the incision are negative; thirdly, if the primary tumor is large, and the abdominal wall muscular tissues that need to be expanded and resected are large, biosynthetic patches should be used to remove the tumor. Thirdly, if the primary tumor is large and more muscle tissue of the abdominal wall needs to be expanded, biosynthetic patches should be used to repair the abdominal wall defects. Up to now, all the patients with abdominal wall sclerofibroma treated by us were satisfied with the safety of the operation, i.e., the complication rate, the recurrence rate, the postoperative appearance of the abdominal wall, and other surgical results.
