We report a case of hemophilic pseudotumor arising in the maxilla of a 46-year-old man with a history of hemophilia A. The initial symptom was painless swelling in the right buccal region. Intraorally, the alveolus was enlarged buccally in the right canine region. A panoramic X-ray film showed a cystlike radiolucent lesion at the apex of the right maxillary canine. Computed tomography showed marked enlargement of the right side of the maxilla and a well-demarcated multilocular radiolucent lesion. A tumor was suspected, and a biopsy was therefore performed during replacement therapy with coagulation factor. The bone cavity contained a hematoma. After the diagnosis of a hemophilic pseudotumor, enucleation was performed. There has been no sign of recurrence in the 3 years after surgery.
