We report four patients with pseudoxanthoma elasticum-like papillary dermal elastolysis (PDE). Multiple small papules on the neck, clinically resembling pseudoxanthoma elasticum, and loss of the elastic fibre network in the papillary dermis were found in each case. Immunohistochemical staining for elastin and fibrillin-1 in one patient demonstrated the disappearance of elastin and fibrillin-1 in the papillary dermis. Site-matched normal skins of the elderly showed intact elastin but a lack of fibrillin-1 in the papillary dermis. The younger normal skins revealed intact elastin and fibrillin-1. The results suggest that fibrillin-1 is absent from the papillary dermis of the normal-appearing neck skin of the elderly and that the primary defect in PDE may be in elastin rather than in fibrillin-1.
