The exact cause of Porokeratotic eccrine ostial and dermal duct nevus is unknown. However, it is believed to be caused by a combination of genetic and environmental factors. It is thought that the condition is caused by a mutation in the gene that controls the development of the eccrine sweat glands. This mutation causes the sweat glands to form abnormally, resulting in the characteristic lesions.

Porokeratotic eccrine ostial and dermal duct nevus (PEDDN) is a rare skin disorder characterized by the presence of small, raised, wart-like lesions on the skin. These lesions are caused by the abnormal growth of the eccrine sweat glands and the dermal ducts that connect them to the surface of the skin. The lesions are usually found on the trunk, arms, and legs, and can range in size from a few millimeters to several centimeters. They are usually asymptomatic, but can sometimes be itchy or painful. Treatment is usually not necessary, but in some cases, topical medications or laser therapy may be used to reduce the size of the lesions.
