[|AI|]  Hi. You haven't mentioned any symptoms associated with the bumps?. According to you, they first appear as small lesions, then they become fluid filled and rupture subsequently and leave behind pigmentation. Are they itchy? Yes /No? Possible diagnosis of recurrent fluid filled lesions appearing on face, arms and legs in a child and resolving with pigmentation is Bulbous pemphigoid or Chronic bulbous disease of childhood or bulbous impetigo. I would advise a skin biopsy from a fresh lesion. That could lead to the correct diagnosis.
