A Case of Submandibular Vascular Malformation with a Phlebolith

Hemangiomas and vascular malformations commonly occur in the extremities and head and neck region, and were previously often referred to collectively as “hemangiomas.” However, it has been proposed that hemangiomas and vascular malformations be distinguished from each other, based on the difference in the vascular endothelial cell dynamics. Most of these diseases in adults that were previously called “hemangiomas” are thought to have been vascular malformations. Herein, we present a case of a vascular malformation in the submandibular region that was accompanied by the formation of internal phleboliths. We report the case here along with a review of the literature.
