| Prurigo nodularis (PN) is a skin condition that causes ulcers after repeated trauma to the skin. Prurigo nodularis itself is not contagious. The cause is unknown. Certain factors cause PN, including nervous and mental disorders, decreased liver and kidney function, and certain skin conditions such as eczema.
Causes. The cause of prurigo nodularis is unknown, although other conditions can cause PN. PN has been associated with Becker’s nevus, linear IgA disease, autoimmune disease, liver disease, and T-lymphocytes.
The exact cause of prurigo nodularis (PN) is not well understood. It is believed that nodules are more likely to form if the skin is scratched or irritated in some way. Hence, a person’s scratching of the skin can cause lumps.
