Haemangioma with Multiple Phleboliths-A Rare Case

Abstract

Haemangiomas and venous malformations are formed due to disturbances during the developmental period of an embryo. Changes in blood flow dynamics within a haemangioma may induce thrombus formation and phleboliths. Inflammation, trauma, debris acting as nidus and vascular lesions have been attributed as principal causes for occurrence of calcifications within the oral mucosa. Occurrence of multiple calcified thrombi (phleboliths) is considered pathognomonic for haemangioma and vascular malformations in the oral and maxillofacial region. We hereby report a rare case of haemangioma associated with multiple phleboliths of the lower lip for seven years. Clinically, it appeared as a smooth circumscribed swelling with mild pain. Excision of lesion was done. Histopathological report showed thin-walled, dilated and congested blood vessels, containing fibrin thrombi in the lumen. Foci of organisation and calcification were seen.
