Abstract* Hemophilic pseudotumor, also called a hemophilic cyst, is a recurrent chronic muscle hematoma and a rare complication of hemophilia. Hemophilic pseudotumor may enlarge progressively and become life-threatening. We report a case of a 3-year-and-3-month-old boy with a mass on his left maxilla for 3 weeks prior. There was a previous history of trauma, but no previous bleeding history, and he had never been diagnosed with hemophilia. Laboratory tests showed prolonged coagulation factor and factor VIII deficiency. The head CT showed an enhancing mass. The patient was diagnosed with hemophilic pseudotumor, and he was successfully treated by administering Factor VIII injections for 7 days. Although rare in developed settings, this case underscores how gaps in awareness of hemophilia in Indonesia can delay diagnosis and allow it to mimic malignancy. Such misrecognition risks unnecessary interventions that may trigger life-threatening bleeding, emphasizing the critical need to strengthen early clinical recognition.
