It is not easy to distinguish the two through visual observation, but you need to consult a doctor to distinguish them with specific etiology and clinical manifestations. The cause of dermatofibrosis is not clear, but it may be related to diabetes and other factors. It is common in middle-aged and elderly people, and can also be seen in women during pregnancy. The main symptoms are filiform, polyp-like masses, soft and inelastic skin, and increased skin color or pigmentation. Patients tend to have no conscious symptoms and have little effect on the body. Warts are benign superfluous organisms caused by human papilloma virus infection of the skin mucosa. The most common types of warts are common warts, plantar warts, flat warts, and condyloma acuminata. Common warts are grayish-brown or brown in color, the size of a soybean, with a rough surface and a hard texture. The plantar warts are usually found on the soles of the feet, mostly on the front of the palm and plantar areas, and are yellowish or brownish in color, with a rough surface and clear boundaries. The skin and warts usually do not affect the life of the patient, and some of them do not require special treatment. If treatment is needed, it is mainly localized. For smaller warts and flaps, physical therapy such as freezing, electrocautery, scraping, and laser treatment may be used. Larger warts can be removed surgically.
