Haemophilic pseudotumour of the mandible: report of three cases.

A haemophilic pseudotumour is basically an encapsulated haematoma. It is an infrequent complication, estimated to affect 1-2% of severe haemophiliacs, although it has also been reported in patients with mild and moderate haemophilia. A history of trauma is reported in most cases, and the onset of symptoms varies from months to years. The majority of haemophilic pseudotumours are seen in adults and occur in long bones (femur, pelvis, tibia). Here are reported three cases of pseudotumour of the mandible in young patients with mild haemophilia A.
