Progressive macular hypomelanosis – http://id.who.int/icd/entity/1864698060

Progressive macular hypomelanosis (PMH) is a common acquired dermatosis occurring in all skin types but most obvious in darker skin types. It is characterised by the progressive appearance of ill‐defined nummular non-scaling macules mainly affecting the trunk. It typically presents in adolescence or early adulthood and then persists. The cause of the pigment loss is unknown but Propionibacterium species have been implicated.
