Peeling skin with leukonychia, acral punctate keratoses, cheilitis, and knuckle pads (PLACK)
Description
Peeling skin syndrome (PSS) is a group of rare autosomal recessive disorders characterized by superficial detachment of the epidermal corneal layers. PSS can be divided into two main types, acral PSS (APSS) and generalized PSS. APSS involves the palmar, plantar and dorsal surfaces of hands and feet. Generalized PSS can be further divided into the non-inflammatory (type A) and the inflammatory (type B) forms. Several underlying genetic causes of PSS have been identified.
