[Lifet-threatening hemorrhage from a mandibular hemangioma].

A case of a nine year-old girl with a life-threatening episode of profuse bleeding after extraction of a loose deciduous molar is reported. An angiography confirmed the presence of a haemangioma in the right side of the mandible. The lesion was superselectively embolized. Two days later exploration of the haemangioma and resection of the bone was performed, and the bleeding stopped. Special concern must be exercised in cases with hypermobility of the teeth, and when episodes of spontaneous haemorrhage are encountered.
