A review of the world literature since 1928 failed to disclose a case of endometriosis affecting the knee. In the case of a 32-year-old women, synovial sarcoma was suspected on the basis of the histologic findings on frozen section, but final pathologic sections showed endometriosis. Synovial sarcoma classically consists if malignant stoma containing gland-like clefts and is easily confused with endometriosis. Affecting the extremities, endometriosis is rare. The condition should new be added to the differential diagnosis of extremity swelling in actively menstruating women.
对1928年以来的世界文献进行回顾，未发现有子宫内膜异位症累及膝关节的病例。在一名32岁女性的病例中，根据冰冻切片的组织学检查结果怀疑为滑膜肉瘤，但最终病理切片显示为子宫内膜异位症。滑膜肉瘤典型地由含有腺样裂隙的恶性瘤体组成，容易与子宫内膜异位症混淆。子宫内膜异位症累及四肢较为罕见。这种情况现在应添加到对处于月经期的女性肢体肿胀进行鉴别诊断的项目中。
