General Discussion

Introduction
Schimmelpenning syndrome is a rare multisystem disorder characterized by sebaceous nevus associated with other abnormalities outside the skin which most commonly affect the brain, eyes and bones. The skin lesions associated with this disorder are called sebaceous nevus because they consist of an increased number of sebaceous glands (small oil-producing glands in the skin) along with an overgrowth (hyperplasia) of the epidermis and dilated apocrine glands. Sebaceous nevus is the most common type of organoid epidermal nevi (which broadly encompass abnormally formed adnexal skin elements such as hair follicles and glands within the skin). Epidermal nevi are usually present at birth (congenital), although they might not be identified until later during childhood or after puberty. Affected individuals may also have abnormalities affecting the brain such as seizures or intellectual impairment, the eyes such as clouding (opacity) of the cornea or partial absence of tissue of the iris or retina (coloboma), and the skeleton such as spinal malformations, craniofacial defects, and deformities of the arms and legs. Schimmelpenning syndrome occurs randomly for no apparent reason (sporadically) during the formation and development of the embryo (embryogenesis), most likely due to a mutation of a gene that occurs after fertilization (postzygotic mutation) and is present in only some of the cells of the body (mosaic pattern).

Summary
In the past, the term "epidermal nevus syndrome" was used to describe Schimmelpenning syndrome. Some authors still use these terms interchangeably. However, epidermal nevus syndrome no longer refers to a single entity, but rather represents a group of distinct, but related multisystem disorders. Additional terms used to describe Schimmelpenning syndrome include nevus sebaceus syndrome, Schimmelpenning-Feuerstein-Mims syndrome, linear sebaceous nevus sequence, nevus sebaceous of Jadassohn, sebaceous nevus syndrome, Jadassohn nevus phacomatosis and Jadassohn sebaceous nevus syndrome.
