Cystic angiomatosis of bone is a rare condition of multifocal angiomas of the skeleton. The condition is believed to be congenital, grows slowly and starts in first decades of life. Two cases of progressive bimaxillary enlargement, presented here with a history of slowly enlargement of facial bones when they were 9 and 6 year old, respectively. Radiographic evaluation of the craniofacial bones revealed aggressive hypertrophy with severe displacement of the teeth. The histopathological evaluation of the gross specimen showed vital bone containing capillary and cavernous spaces with endothelial lining. Aggressive cystic angiomatosis of the facial bones was described here as the most probable diagnosis.
