My 1.5 year old had 2 itchy spots on his trunk which he started scratching in March, which later developed into papules, grew in size and turned into a hyper pigmented plaques/lesions after applying topical corticosteroids for the past 2 months. One flattened and the other didn't and both are very itchy. He also had a secondary papular rash that started 3 days after the first 2 dveloped into papules and this rash was all over his body and super itchy which is brought under control upto 90% with topical corticosteroid usage for 5 weeks. I haven't applied any ointment on rest of his body except for the 2 big lesions in the past 3 weeks. Using vaseline to moisturize and wet wrapping to soothe his skin. He is still very itchy all over his body and tends to develop papular rash wherever he scratches. I'm forced to dress him in full sleeves and full pants through hot summer to prevent him from scratching. We haven't got any official diagnosis. What could these be?
