Inguinal endometriosis is a less common form of endometriosis. Therefore, there is no consensus regarding its pathogenesis or treatment. In this study, we retrospectively reviewed the pathogenesis and treatment of six cases of inguinal endometriosis in our facility between 2009 and 2019. The pathogenesis of inguinal endometriosis is believed to involve hematogenous and lymphogenous extensions, as well as direct infiltration from the canal of Nuck or inguinal hernia. However, in our cases, the endometriotic lesions might have spread intravascularly from the uterine cavity. The lesions in our all cases were found as nodular or pointed hyperintensities on T1-weighted magnetic resonance imaging. In addition, all the patients experienced swelling and pain in the inguinal region during menstruation. Complete resection is often performed; however, hormonal therapy is administered to patients who do not undergo surgery, or to avoid recurrence. In our cases, dienogest was effective in reducing inguinal endometriotic lesions, improving pain, and preventing recurrence.
腹股沟子宫内膜异位症是一种较罕见的子宫内膜异位症形式。因此，关于其发病机制或治疗方法尚无共识。在本研究中，我们回顾性分析了2009年至2019年间我院6例腹股沟子宫内膜异位症的发病机制及治疗情况。腹股沟子宫内膜异位症的发病机制被认为涉及血行和淋巴转移，以及来自Nuck管或腹股沟疝的直接浸润。然而，在我们的病例中，子宫内膜异位病变可能是从子宫腔经血管扩散而来。我们所有病例的病变在T1加权磁共振成像上均表现为结节状或尖状高信号。此外，所有患者在月经期间腹股沟区均出现肿胀和疼痛。通常会进行完整切除；然而，对于未接受手术的患者或为避免复发，会给予激素治疗。在我们的病例中，地诺孕素在减少腹股沟子宫内膜异位病变、改善疼痛和预防复发方面有效。
