Skin ulcers are generally localized skin tissue defects caused by traumatic microbial infections, tumors, circulatory disorders and neurological dysfunction, immune dysfunction or congenital skin defects. Traumatic ulcers are often caused by physical and chemical factors acting directly on tissues. Microbial infectious diseases are caused by bacteria, fungal spirochetes, viruses, etc., causing tissue destruction, nodules or tumor rupture. An inflammatory vascular ulcer caused by an abnormal immune system.

Cause

Skin ulcers are generally localized skin tissue defects caused by traumatic microbial infections, tumors, circulatory disorders and neurological dysfunction, immune dysfunction or congenital skin defects. Traumatic ulcers are often caused by physical and chemical factors acting directly on tissues. Microbial infectious diseases are caused by bacteria, fungal spirochetes, viruses, etc., causing tissue destruction, nodules or tumor rupture. An vascular inflammatory ulcer caused by an immune abnormality is formed by necrosis of tissue due to arterial or arteritis. Circulatory or neurological dysfunction is a tissue disorder caused by dystrophic disorders such as varicose veins, leprosy, ulcers, etc.
