Spontaneous bone regeneration in a large haemophilic pseudotumour of mandible

Pseudotumours of haemophilia (PTH) are locally expansile destructive haematomas which result in varying morbidity among haemophilic patients. Adequate haematological treatment and prophylaxis helps in preventing these haematomas. Currently, there is no uniform standard management protocol for this entity due to rarity of these lesions. PTH are seen in 1%–2% of the severe haemophilic patients. They may also be seen in moderate cases when adequate factor coverage is not provided or in cases with factor VIII inhibitors. We report a rare case of mandibular pseudotumour in a patient with moderate haemophilia and Glanzmann's thrombasthenia, treated successfully with decompression of the haematoma. Postdecompression, sequential radiography revealed spontaneous bone regeneration at the site of the lesion. With 2 years follow-up, the mandible had no residual lesion. This reveals the role and potential of conservative decompression even in cases with severe osteodestruction secondary to developing haematoma of the mandible in haemophilic patients.
