An 8-month-old infant presents to the pediatric dermatology clinic with his mother for the evaluation of dry scaly skin that has been unresponsive to topical emollients.
The patient’s mother states that he has had dry scaly skin for most of his life, but it has never been as severe as this. She also notes a birthing history of prolonged labor, resulting in cesarean section.
On examination, there are dark brown adherent scales on the extremities, trunk and neck with sparing of the face, palms, soles and skinfolds.
What’s the diagnosis ?
