Peeling skin syndrome is a rare genodermatosis with variable age of onset from birth to adulthood. Clinically, it is characterized by a pruritic or nonpruritic spontaneous superficial peeling of the skin, which sometimes is accompanied by erythema or vesiculation. The skin involvement is usually general, but in some patients the scalp, face, palms, and soles may be unaffected. Seasonal changes have been reported. The histologic picture is characterized by separation of the epidermis between the statum corneum and the stratum granulosum (summary by Hacham-Zadeh and Holubar, 1985). Generalized PSS has been subclassified into a noninflammatory type, designated type A, and an inflammatory type, designated type B (Traupe, 1989; Judge et al., 2004). Type B, in which generalized peeling skin is associated with pruritus and atopy, is characterized by lifelong patchy peeling of the entire skin with onset at birth or shortly thereafter. Several patients have been reported with high IgE levels (summary by Oji et al., 2010). Type A, a continuous nonerythematous exfoliation, is usually congenital or appears during childhood (summary by Mallet et al., 2013). Genetic Heterogeneity of Peeling Skin Syndrome Peeling skin syndrome-2 (PSS2; 609796), an acral form of the disorder that mainly involves palmar and plantar skin, is caused by mutation in the TGM5 gene (603805) on chromosome 15q15. Peeling skin syndrome-3 (PSS3; 616265) has been mapped to chromosome 19q13. Peeling skin syndrome-4 (PSS4; 607936) is caused by mutation in the CSTA gene (184600) on chromosome 3q21. Peeling skin syndrome-5 (PSS5; 617115) is caused by mutation in the SERPINB8 gene (601697) on chromosome 18q22. PSS6 (618084) is caused by mutation in the FLG2 gene (616284) on chromosome 1q21. [from OMIM]

A group of rare autosomal recessive forms of ichthyosis with clinical characteristics of superficial, asymptomatic, spontaneous peeling of the skin and histologically by a shedding of the outer layers of the epidermis. Presents with either an acral or a generalised distribution. [from SNOMEDCT_US]

Potocki-Shaffer syndrome is a rare contiguous gene deletion syndrome due to haploinsufficiency of the 11p12-p11.2 region and is characterized by craniofacial abnormalities, developmental delay, intellectual disability, multiple exostoses (168500), and biparietal foramina (609597) (summary by Swarr et al., 2010). [from OMIM]

A form of peeling skin syndrome that presents with a generalized distribution. It comprises two sub-types: the non-inflammatory (PSS type A) and the inflammatory (PSS type B) forms. [from SNOMEDCT_US]
