Young Boy With Unilateral Facial Flushing

A 2-year-old previously healthy boy was referred to the emergency department (ED) by his pediatrician after an unusual pattern of facial flushing and sweating was observed after he had played outside earlier in the day (Figure 1). His skin color returned to normal within several minutes. In the ED, the child was happy and playful, with normal vital signs. He had anisocoria, with the left pupil larger than the right, which became more pronounced in dim lighting. He had no iris heterochromia and no ptosis.
