Buccal hemangioma with phleboliths. Report of two cases.

Two cases of buccal hemangioma with phleboliths were reported. Angiography, angioxerography, and computerized tomography were carried out before the procedures were planned. One patient was treated by means of surgical excision of the tumor after ligation of the left external carotid artery. The second patient was treated by means of surgical excision alone. Histologic examinations suggested that the thrombi in the blood vessels of hemangiomas might become the core of the phleboliths. Analysis of the phleboliths by means of x-ray diffraction and infrared spectrometry confirmed calcium phosphate and calcium carbonate as the main components of the phleboliths.
