Hi, my 2 y.o. son had many very small papules on one side of his scrotum. I noticed them 2 weeks ago. I was applying sudocream for a few days , then I used( three times ) pimafucort. Now, they are almost disapear but he has developed a few bigger size papules in folds (groin area) his legs. When I was looking through pictures on Google, I think papules look a bit like hot tube rash. They are red, rised, approximate 2mm in diameter. Some of them have signs of keratosis(dryness). What can it be?
