INTRODUCTION: Synovial hemangioma is a rare intra-articular benign tumor that is difficult to diagnose because of its nonspecific symptoms. Patients are generally children or young adults with a nontraumatic recurrent swollen painful knee. CASE PRESENTATION: A 24-year-old woman presented with a 20-year history of recurrent pain and swelling in the right knee. Physical examination revealed a small painful point adjacent to the medial side of the patella. Magnetic resonance imaging revealed an intra-articular tumor. After arthroscopic examination, surgical excision was performed. The histology was characteristic of synovial hemangioma. RESULTS: Open complete synovectomy of the circumscribed capillary hemangioma was successful, and the patient remains asymptomatic 2 years after surgery.
