hemophilic pseudotumor in the jawbone: a case report and literature review

Background: hemophilic pseudotumor is a rare lesion that is progressive and expansile by nature. it is a hematoma or a blood cyst surrounded by a fibrous capsule. case report: a 7-years-old boy was referred with a painless swelling in the mandible, bleeding and problem in mastication. due to a late diagnosis, the patient went untreated for almost a year. after detailed examination and taking medical history as well as paraclinical investigations, including panoramic x-ray, ct (computed tomography), cone-beam ct, and angiography along with laboratory tests, a hemophilic pseudotumor was diagnosed. treatment plan was set to curettage, coagulation factor injection and regular follow-up. the prognosis was satisfactory and the patient made a full recovery within a year. conclusion: a hemophilic pseudotumor is very rare in the jaw and can be diagnosed as a benign or malignant tumor due to its nonspecific radiographic features. invasive treatment may result in severe bleeding or even death. therefore, knowledge of the lesion is a prerequisite for careful diagnosis and treatment.
