Vascular anomalies arising in the mandible comprise under 1% of all intraosseous tumors originating from the mandible, and their occurrence is extremely rare. Few pediatric cases of mandibular capillary vascular malformations have been reported. We report two pediatric intraosseous capillary mandibular malformations with a similar clinical course. A 15-year-old boy and 10-year-old girl each developed a painless, rapidly growing mandibular swelling. Imaging and tissue biopsy did not establish a definitive diagnosis. As the destruction of the mandible progressed, mandibular resection and reconstruction were performed, and capillary malformation was diagnosed on the grounds of tissue examination. There has been no postoperative recurrence, and good function and appearance have been maintained. Mandibular vascular malformations require prompt, appropriate diagnosis and treatment because bone destruction progresses as the lesions grow. Although the surgical treatment of pediatric vascular malformations involves various problems peculiar to the growth phase, it is important to consider resection, including reconstruction, so that the postoperative function and appearance are not impaired. Level of evidence: Level V, therapeutic study.
