Abstract：
BACKGROUND: Inguinal endometriosis is one of the most common forms of endometriosis. The present study introduces 8 cases of inguinal endometriosis and discusses probable theories of inguinal endometriosis by reviewing the literature.
METHODS: 8 Iranian cases of inguinal endometriosis with a mean age of 36 years were presented. Catamenial groin pain and swelling were the most common complications. Also, patients usually had accompanying symptoms such as pelvic pain and dysmenorrhea. One-half of patients had a history of previous abdominal surgery. Ultrasound was diagnostic in 4 patients (50%), and magnetic resonance imaging was used in two patients (25%). Among 6 patients who underwent hormonal therapy, 4 experienced an endometriosis size increase. Inguinal endometriosis was right-sided in 87.5% of patients, and among 4 patients who underwent surgery, 75% had proximal site involvement of the round ligament.
CONCLUSIONS: According to the rarity of inguinal endometriosis, it is more likely to be a misdiagnosis with other inguinal disorders such as inguinal hernia. Inguinal endometriosis should be considered in patients who undergo inguinal herniorrhaphy, with suspected findings such as thickening of the hernia sac wall, bloody fluid inside the sac, or thickening of the extraperitoneal round ligament during the surgery.

摘要：
背景：腹股沟子宫内膜异位症是最常见的子宫内膜异位症之一。本研究介绍了8例腹股沟子宫内膜异位症，并通过文献复习讨论了腹股沟子宫内膜异位症的可能理论。
方法：介绍了8例伊朗腹股沟子宫内膜异位症患者，平均年龄为36岁。月经性腹股沟疼痛和肿胀是最常见的并发症。此外，患者通常伴有盆腔疼痛和痛经等症状。一半的患者有腹部手术史。超声诊断4例（50%），2例患者（25%）使用磁共振成像。在6名接受激素治疗的患者中，4经历了子宫内膜异位症大小增加。在87.5%的患者中，腹股沟子宫内膜异位症为右侧，在接受手术的4名患者中，75％的圆韧带近端受累。
结论：根据腹股沟子宫内膜异位症的罕见性，更有可能误诊为腹股沟疝等其他腹股沟疾病。腹股沟疝修补术患者应考虑腹股沟子宫内膜异位症，怀疑有疝囊壁增厚等发现，囊内有血的液体,或在手术过程中腹膜外圆韧带增厚。
