There are many possible reasons for a bulge in scapula, including lipoma, bursitis, scapula misalignment and so on. 1. Lipoma: clinically more common, mainly manifested as a lump, no redness, heat, pain, local skin is normal, the lump is not adherent to the skin, the lump has a clear boundary, soft texture, mostly benign tumors. 2. Bursitis: because chronic strain triggers aseptic inflammation of the bursa, the fluid in the bursa is increasing, resulting in cysts in the scapula area. 3. Scapular misalignment: mostly caused by trauma, resulting in scapular deformation, local soft tissue hematoma, resulting in scapular bulge. There are many other reasons for scapula bulge, such as fibroma, osteochondroma, osteosarcoma, etc. It is recommended to consult a doctor in time to clarify the cause of the disease before treatment.
