By definition, a cyst is any cavity that is lined by an epithelium. Cysts may be found in virtually any organ in the body and are often lined by epithelium that is native to that particular organ. Although cysts may be classified on the basis of several different criteria, the diagnosis of cutaneous cysts is predominantly based on the nature of the epithelial lining. Recognition of the nature of the epithelial cyst wall lining is also important for understanding the histopathogenesis of these lesions, which usually arise from normal counterparts in the skin, predominantly adnexal structures.
