title: Tufted angioma with complete regression.
abstract: We describe 2 patients with tufted angioma (angioblastoma of Nakagawa) which regressed spontaneously. Both patients had a solitary but large lesion on the trunk. The 1st patient, a 3-month-old girl, presented with a 6-cm plaque which began to regress 2 years later. It regressed completely over 1 year and had not recurred after a further 6-year follow-up. The other patient, a 3-month-old boy, presented with a 12-cm mass of coalescent angiomatous papules which slowly regressed over 3-years, while small new lesions appeared in the adjacent contiguous skin. Eventually, gradual and near complete regression was observed after 8 years. The histology in both cases was typical, but bore some resemblance to the recently described kaposiform hemangioendothelioma, lobular capillary hemangioma and spindle cell hemangioendothelioma.
