Beginning with this issue of Acta Dermato-Venereologica, the Editorial Board has decided to launch a series of theme issues, whereby regular papers on similar topics are published together instead of appearing chronologically (and hence dispersed) based solely on the date of acceptance. Needless to say, these themes, just as in the present issue, will be complemented by other review articles and original papers that either do not fit with the chosen theme or that represent fast-track publications that cannot await the appearance of a suitable theme.
