The difference between subcutaneous nodules and lymph nodes is as follows: 1. Subcutaneous nodules: grow in the subcutaneous tissue, there is a close relationship with the skin, and can not be pushed by hand; 2. Lymph nodes: grow in the lymphatic channels, mostly on the deep side of the skin, and can be pushed by hand. Larger lymph nodes that are adherent to the surrounding skin generally have poor mobility and cannot be pushed by hand. For nodules with a diameter of more than 1cm and poor mobility, it is recommended that patients go to the hospital for an early checkup, and choose different departments for consultation according to the location of the nodules. Head and face nodules are recommended to consult the Department of Ear, Nose and Throat, Head and Neck Surgery; trunk nodules are recommended to consult the Department of General Surgery; and limb skin nodules are recommended to consult the Department of Orthopaedics to clarify the type of the nodules through further examination.
