Tufted angioma of adult onset, revealing abundant eccrine glands and central regression.

Tufted angioma (angioblastoma) usually occurs in infancy. Some lesions reveal proliferation of eccrine glands and some undergo spontaneous regression. We report a lesion from the left lateral chest of a 58-year-old male, which had appeared 5 years ago and gradually increased in size. Its color had faded out centrally. Histological examination showed many angiomatous lobules on the border of the lesion but few in the central portion. Abundant eccrine sweat glands, small venules and dense connective tissue were seen in both areas. The histology and the clinical course suggested that central regression occurred in the lesion. Out of 211 reported cases, we found 4 cases that had annular lesions spreading centrifugally. Though these lesions were not examined histologically, they were suspected to regress in the central portions. We suggest that central regression can rarely occur in tufted angioma. Copyright 2000 S.
