To the Editor.—
We describe a case of congenital Horner's syndrome affecting a 4-year-old boy with a complaint of one-sided flushing of the face. Although this very rare disease has not been reported before in the dermatologic literature, we should remember that the patient with one-sided flushing might have congenital Horner's syndrome.
Report of a Case.—
A 4-year-old boy was brought to us by his mother because she noticed that the right side of his face became flushed after exercise. His mother was also aware that sweat was not coming from the left side of his face. His delivery had been spontaneous by the vertex, with a birthweight of 2565 g at 40 weeks' gestation. There was no evidence of brachial plexus lesion or any untoward event in the newborn period. At the first consultation, he had a normal skin color on both sides of his face. After 10 minutes
