nodular fasciitis
Introduction
Introduction to nodular fasciitis Nodular fasciitis is a rapidly growing, self-limiting, superficial fascia nodular fibroblastic proliferative lesion with reactive and self-limiting properties, also known as pseudosarcoma fasciitis. It is a solid single nodule, sometimes tender, located in the deep sarcolemma and often extends to the subcutaneous tissue. The incidence of both sexes is equal, with an average age of onset of 40 years. Because nodular fasciitis is a non-neoplastic lesion. Western medicine treatment is mainly surgical resection, the recurrence rate is low, no more than 1 to 2%, and a small number of patients can disappear by themselves. basic knowledge The proportion of illness: 0.02%-0.03% Susceptible population: average age of onset is 40 years old Mode of infection: non-infectious Complications: leiomyosarcoma
Cause
Cause of nodular fasciitis
Trauma factors (40%):
Acute or chronic injury or strain of the muscles, ligaments, and joint capsules of the shoulder and neck is the basic cause of the disease. Trauma causes the muscles to be inactive, and the capillaries and microcirculation are not smooth, leading to the disease. Trauma at birth is a causative factor in cranial fasciitis.
Other factors (20%):
Nodular fasciitis refers to the aseptic inflammatory reaction of muscles and fascia. When the body is stimulated by external factors such as cold, fatigue or improper sleeping position, it can induce an acute attack of nodular fasciitis. Chronic muscle pain, soreness and weakness can be repeated due to repeated stress or cold and other unpleasant stimuli due to repeated treatment in the acute phase.
Prevention
Nodular fasciitis prevention
1, long-term sedentary office staff should rest regularly, so that the tension of the back muscles can be alleviated. Should reduce the number of sports such as jumping, running, long walks and so on.
2, usually pay attention to sitting posture, sitting for an hour after a long time.
3, to avoid sleeping on a soft bed, you should choose a hard bed.
4, pay attention to cold and moisture. Warm feet can be used every night to promote local blood circulation.
5. Actively strengthen the muscles of the lower back muscles. Older people should choose softer shoes, such as casual shoes, and wear them for a long time.
6, acute lumbar sprain should be actively treated, rest assured to prevent chronic changes.
7. When preparing for sports or strenuous activities, be prepared for activities.
8, to prevent overwork, people like a machine, excessive operation or overloaded use, will inevitably lead to damage to certain parts or the entire machine. As the center of human body movement, the waist is overworked, which inevitably causes injury and low back pain. Therefore, pay attention to work and labor in all work or labor.
9, pay attention to weight loss, weight control, the body is too fat, will inevitably bring additional burden to the waist, especially middle-aged people and women postpartum, are easy to gain weight, temperate diet, strengthen exercise is necessary.
10, moderation of the house, "waist is the house of the kidneys", the frequency of sexual intercourse must be detrimental to the kidney, kidney loss is low back pain.
Complication
Nodular fasciitis complications Complications leiomyosarcoma
The common complication of this disease is sarcoma.
Symptom
Nodular fasciitis symptoms Common symptoms Nodular fascia pain Shoulder and back muscle pain Subcutaneous deep fascia... Gray-white nodular superficial fasciitis painful part of the pain
The disease is more common in adults, 20 to 40 years old is the most common, 20 to 30 years old is the peak incidence. Although nodular fasciitis can occur in any part of the body, the forearm of the upper limb is the most common, followed by the chest and wall of the head and neck, the trunk and the back. There are two most important clinical manifestations of the disease: one is a rapidly growing mass, usually a small mass or nodule within 1 to 2 weeks, the lesion may be accompanied by pain, numbness or paresthesia; the second is usually a small mass , generally no more than two centimeters, and the lesions are self-limiting. Nodular fasciitis is located in the superficial fascia. The lesion can invade the skin and muscles, showing invasive growth, and there is no envelope around.
Examine
Examination of nodular fasciitis
Eye view
The mass is nodular, round or oval, and the nodules are often connected to the superficial fascia or deep fascia, without a capsule and small volume. The slices are light red or tan, with a jelly-like or mucoid-like area, and some contain adipose tissue or hard fiber cord-like stripes.
2. Microscopic examination
The lesion is mainly fibroblast proliferation. In early lesions, the newly born fibroblasts are polygonal, round or oval, and later become long fusiform. The cell boundary is not clear, the cytoplasm is reddish, sometimes fine particles are visible, and the nucleus is generally obese, oval-shaped and deeply stained. Some nucleoli are clear, most of them see mitotic figures, only a few see pathological mitotic figures, proliferating fibroblasts are mildly heteromorphic, dense and dense, arranged without a certain direction, each can be with the surrounding fascia, Muscle bundle anastomosis.
Diagnosis
Diagnosis and differentiation of nodular fasciitis
This disease is difficult to diagnose before surgery. Those with the following characteristics should consider this disease:
1. This disease occurs mostly in the 30 to 40 years old.
2. The course of disease is shorter.
3. Most patients have a history of trauma.
4. Occurs in the limbs, especially in the forearm.
5. More manifestations of a single-fold rapidly increasing subcutaneous mass, more active, no adhesion to the skin, the boundaries of the examination of the mass is unclear, head and neck, breast or even the vulva can also occur.
6. The mass may have local pain or tenderness.
7. X-ray examination has nothing to do with bone tissue.
