Hemangiomas are benign vasoformative neoplasms or developmental conditions of endothelial origin. Synovial hemangiomas arise from a synovial lined surface within a joint space. This report describes a case of synovial hemangioma of the left temporomandibular joint (TMJ) in a 65-year-old male patient. Histologic examination confirmed the diagnosis of synovial hemangioma. This is a rare case series, as the only case of synovial hemangioma with TMJ localization previously described was reported in 1988.
血管瘤是起源于内皮细胞的良性血管形成性肿瘤或发育性病变。滑膜血管瘤起源于关节腔内滑膜衬覆的表面。本报告描述了一例发生于 65 岁男性左侧颞下颌关节（TMJ）的滑膜血管瘤病例。组织学检查证实了滑膜血管瘤的诊断。这是一个罕见的病例系列，因为此前仅在 1988 年有报道过一例 TMJ 定位的滑膜血管瘤病例。
