Lipoma is a benign lesion that is formed when fat grows under the skin or inside the muscle, and is covered by a thin layer of connective tissue. If the lipoma is small and painless, surgery may be unnecessary for the time being. If the larger lipoma causes pain or pressure and affects the movement of the shoulder joint, surgery may be necessary. It can be removed under local anesthesia. After surgery, the wound should be routinely sent for pathological examination and stitched up. If the hemangioma is soft, the mass will disappear when pressed by hand, but it will reappear when you release your hand. If the hemangioma is confirmed, we recommend surgery to remove it. It is possible that the hemangioma will increase in size over time and may grow into the gap of the shoulder joint, thus affecting the movement of the shoulder joint.
