Hemangiolymphangioma is a malformation of both lymphatic and blood vessels. While a hemangiolymphangioma is a benign lesion, its propensity to invade underlying tissues and to recur locally distinguishes it from the simple lymphangioma or hemangioma. Hemangiolymphangiomas are uncommon developmental anomalies and intraosseous hemangiolymphangioma of the mandible is a relatively rare condition: when it occurs, the clinical and radiographic presentation are often nonspecific. The author presents a case of hemangiolymphangioma in mandible.
