instruction: hello this is not an average question but I hope someone may help me a few months ago I have been diagnosed with atypical dermatitis my symptoms were red spots regularly appearing and disappearing they were not itchy except slightly on the scalp and forefront shower was exacerbating the symptoms for about 30 min but a reaction to shampoo and soap were excluded as this was happening even only with water I took oral antifungal on go prescription but nothing changed now for the weird part I work as a pod student in preclinical oncology I often work with mice and I realized that some of the mice I came in contact with were developing red spots the only difference is that while my spots are slightly swallowed on the mice they are deep like the outer layer of the skin is missing the vet said they are not in pain they seem not to spread the disease g mice per cage only with symptoms for several months this happens only on mice I came in contact with the spots on mice extend with time up to 20 of the skin surface for what we observed but causing no mortality the mice used here are mri nude mice lacking linfocytes I think an atypical dermatitis is not contagious so how could it be could my diagnosis be wrong or are the spots on the mice an uncorrelated thing than you in advance for any help
