Acquired "tufted" angioma (progressive capillary hemangioma). A distinctive clinicopathologic entity related to lobular capillary hemangioma.
American Journal of Dermatopathology 1987 August
Three young patients affected by intradermal and subcutaneous vascular proliferations are presented. The lesions were acquired and developed as solitary or multiple erythematous patches and plaques in the upper thorax, neck, and scalp. Light-microscopic examination revealed a deep-seated vascular growth with a distinctly lobular pattern. Ultrastructural and immunocytochemical studies demonstrated the cellular proliferation to be composed of endothelial and perithelial cells, the latter predominating. These cases are interpreted as examples of the vascular disorder described as progressive capillary hemangioma and acquired "tufted" angioma. We believe that it represents a distinctive clinicopathologic entity that is closely related histogenetically and perhaps pathogenetically to the entity recently renamed lobular capillary hemangioma.
