Neck spurs may be caused by filiform warts, common warts, soft tissue fibroma of the skin and other conditions. 1. Filiform warts: a benign disease caused by human papilloma virus infection, clinically more common, can be transmitted through direct or indirect contact. The skin on the neck is relatively thin compared to other places, and after the skin is damaged, the human papilloma virus will enter the basal layer of the epidermis, leading to the formation of filiform warts. 2. common warts: mainly caused by human papilloma virus infection, there will be raised wart-like growths on the skin, the surface is rough, can exist for a long time, but also can gradually subside, and warts can be increased with the progress of the disease. 3. Skin soft tissue fibroma: also known as skin flab, the etiology is still unclear, but may be related to viral infections, diabetes, obesity and other factors. The condition can also lead to neck spurs, but there are usually no obvious painful symptoms. There may be other reasons for neck spurs, and it is recommended that the patient go to the hospital in a timely manner to clarify the cause of the disease and follow the doctor’s instructions for symptomatic treatment to avoid delays in the condition.
