title: Persistent linear bands in infancy acquired after local pressure: a consequence of mast cell activation?
abstract: A 10-month-old girl with marked symptomatic dermographism presented with linear bands at the sock line noted to have developed following an episode of localized urticaria and angioedema at the sock line. We speculate that release of mast cell mediators associated with the dermographism may have triggered the development of the linear bands.
