title: A new type of telangiectasia following trauma.
abstract: Three patients are reported, each with a reddish macule or plaque (7-10 mm) induced by trauma. The histology of these lesions showed hyperkeratosis, acanthosis and marked dilation of vessels in the papillary to deep dermis. The electron microscopic study revealed a layer of endothelial cells surrounding the dilated vessels, suggestive of telangiectasia. The relationship between this entity and solitary angiokeratoma is discussed.
