definitionHemangiomas, which are benign developmental vascular tumours, have an initial proliferative and a later involutional phase. Most of them undergo complete or partial resolution. When resolution has ceased, the affected area may be perfectly normal, but more commonly it shows subtle atrophy and telangiectasia. At certain sites, particularly the lips and the eyelids, residual sacs of redundant skin vessels are common. | synonymsHemangioma, State after Regression |
