Muscle fibroma usually occurs in the limbs, especially in the lower limbs and upper limbs above the elbow, part of the patients will occur in the back, and some patients will occur in the rectus abdominis muscle. Clinically, there are several obvious symptoms: firstly, there are obvious nodules under the skin, which are smooth and oval in shape, deep to the muscle layer without adhesion to the skin, and can be pushed a little bit, and the skin is the same color as the normal one. Secondly, patients usually have no obvious discomfort, and a few patients may have localized pressure pain.
