strange patches in English bulldog puppy

Hi, my 5 month old english bulldog puppy has been full of these non itchy "plaques" for about 2-3 months.. The puppy is active and lively, she eats hypoallergenic kibble regularly and has been on zinc supplements and multivitamins for a month now. Initially (a month ago) they were treated like mushrooms with regular antifungal and antibiotic therapy but nothing, indeed they seem to have increased (initially they are half a centimeter red points which then tend to widen), she also has one in the inner ear and some in the genital .. they told me to wait mid-January to perform histological examination. I don't know if a case like this has ever happened to you and it is really disheartening not to have a diagnosis or to hypothesize nasty pathologies such as "mastocytomas", "epidermolysis bullosa", etc. by the local vets. I am attaching pictures of the puppy. Thanks in advance if you can suggest anything
