A hypertrophic hemangioma of a 6-month-old girl was studied electron-microscopically. Hypertrophic hemangioma is characterized by few patent vessels, high cellularity, local aggressiveness, occasional mitotic figures and frequent recurrence after operation. The ultrastructural examination showed the tumor to be composed of three types of cells: endothelial cells, pericytes and phagocytic fibroblasts.
