Review Question - QID 207816

A 1-week old child is brought into your office for a normal check-up when you notice bruising on his arm. The mother states the child was born at home and had a "natural birth". She also states that the child is eating and having yellow seedy stools 4-8 times per day. She took lamotrigine for her seizures, but she had regular check-ups and was told everything was normal. She does state that she has noticed that the child bruises easily. On exam, the vitals are normal, but the child has pin-point spots on his arms where he was held by the mother that do not disappear with pressure (Figure A). His PT and aPTT are elevated, but the bleeding time is normal. What is the most likely diagnosis?
