Case 1
A 19-year-old woman had several episodes of pain, swelling, and occasional buckling of her right knee of 5 years of duration. She pointed out that she sometimes needed to use crutches to walk. There was no history of trauma. A subcutaneous hemangioma was observed in the physical examination of the infrapatellar and popliteal region (Fig 1).Swelling with tenderness was localized to the suprapatellar pouch. Arthrocentesis confirmed
Discussion
Intra-articular hemangioma is a well-known but rare lesion that arises from any synovium-lined surface. The most typical form of synovial hemangioma is the intra-articular type in which the tumor forms a mass lined by synovial membrane. These tumors almost invariably involve the knee joint. However they have also been found in the elbow,8, 15 wrist, and ankle,8 as well as in the tendon sheath.16 There is a slight preponderance of female to male patients in the literature.17 This lesion has been

2012, Egyptian RheumatologistCitation Excerpt :The tumor is observed in two different forms: the synovial hemangioma or the arteriovenous malformation named also as hemangiohamartomas. They may cause hemorrhagic synovitis and arthropathy, probably as a result of recurrent episodes of intra-articular bleeding and mechanical irritation [5], they may be also relatively painless tumors [6]. Cavernous hemangioma may enter the differential diagnosis of other lesions encountered more frequently in clinical practice, including pigmented villonodular synovitis and traumatic hemarthrosis [7].
