@drderrickphillips: Think those lighter patches on your back are a fungal infection? Not always. This is progressive macular hypomelanosis. A condition that causes lighter patches, usually on the lower back or abdomen. It’s often confused with pityriasis versicolor, a fungal rash. In both conditions, the lighter colour is due to reduced pigment, but the cause is different. • Pityriasis versicolor: yeast interferes with pigment • Progressive macular hypomelanosis: likely linked to Cutibacterium acnes Because they look so similar, it’s easy to misdiagnose, and the treatment approach is different. #pigmentation #skinhealth #dermatologist
