Abstract

Pseudoxanthoma elasticum (PXE) is a disease characterized by aberrant mineralization of soft tissue and fragmentation of elastic fibres. It is often difficult to distinguish PXE clinically from pseudoxanthoma elasticum-like papillary dermal elastolysis (PXE-like PDE). However, we have identified that the dermoscopic findings in PXE include coalescing and reticulated yellow-white clods on a light purple-red background, whereas the dermoscopic findings in PXE-like PDE lack such a coloured background. To our knowledge, this is the first detailed description of dermoscopic differences between PXE and PXE-like PDE.
