Living young cases tell us that there is a great need to increase public attention and awareness of the rare disease of abdominal wall sclerofibroma. Abdominal wall sclerofibroma, also known as ligament-like fibroma of the abdominal wall, is clinically rare, with an incidence of 0.2-0.4 per 100,000 reported. Abdominal wall sclerosing fibroma is histologically a benign tumor, but its biological behavior is malignant. It is generally non-metastatic, but has a high recurrence rate, which can be as high as 70% after local excision. The cause of its pathogenesis is still unclear, most scholars report that it is related to trauma, and the tumor is mostly found in the original surgical incision and adjacent areas, and most of them are females, especially women of childbearing age, aged 25-37 years old, with a history of surgery. Some scholars believe that pregnancy and childbirth are also a kind of trauma, because the prolonged overstretching of the abdominal muscles during pregnancy and the continuous and violent contraction of the abdominal muscles during childbirth can cause trauma to the fibers and lead to tumorigenesis. However, we recently treated an 18-year-old girl who was not yet married and had no history of trauma, but grew such a huge abdominal wall rigid fibrous tumor, which is clinically rare. Happily, with the development of medicine and new materials science, this disease is no longer difficult to treat. However, we need to pay attention to two points: firstly, don’t fall into the misunderstanding that you can’t get out of the tumor, this tumor is not the other tumor, it belongs to the category of abdominal wall surgery and can only be surgically resected, and other methods such as radiotherapy and chemotherapy can’t benefit the patient and can’t stop the tumor from growing; secondly, don’t give up so easily, and it should be detected and treated as early as possible, the earlier, the better. Clinical practice has proved that the recurrence rate can be reduced to 4% if detected early and resected cleanly.
