Echoing others, but not even rare diseases. I had perioral dermatitis, first result on google for the symptoms. I went to 4 dermatologists over 4-5 months who failed to diagnose it, assuring me it absolutely wasn't a fungus, instead telling me it was eczema and prescribing topical steroids (as is their wont). The real solution was washing my face a bit more.
