Dermoscopic features of pseudoxanthoma elasticum

Summary 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 .
