We report a case with inguinal subcutaneous endometriosis without typical cyclic dysmenorrhea and accompanied with a hernia sac treated with resection of the tumor and herniorrhaphy.
A 40-year-old woman had a painless enlarged inguinal nodule for 3 months.
Subcutaneous endometriosis accompanied with a hernia sac.
Ultrasonography showed a hypoechoic lesion (3.0 cm × 2.0 cm), and an inguinal subcutaneous tumor was first suspected. After surgical exploration, a cystic lesion was excised and the hernia hole was repaired by herniorrhaphy. The immunohistochemical analysis of the small endometriotic cyst-like lesion revealed calretinin (-) in epithelial cells and CD10 (+) in stromal cells, indicative of subcutaneous endometriosis accompanied with a hernia sac.
The patient was followed up for 1 year and without recurrence.
Cutaneous endometriosis accompanied with a hernia sac can be presented without typical endometriosis-associated symptoms such as dysmenorrhea. Inguinal endometriosis might be the differential diagnosis of inguinal painless nodules.
我们报告了一例腹股沟皮下子宫内膜异位症病例，该患者无典型的周期性痛经，伴有疝囊，采用肿瘤切除和疝修补术治疗。
一名 40 岁女性因无痛性腹股沟结节增大 3 个月就诊。
皮下子宫内膜异位症伴疝囊。
超声显示低回声病变（3.0×2.0cm），首先怀疑腹股沟皮下肿瘤。手术探查后切除囊性病变，通过疝修补术修复疝孔。小的子宫内膜异位囊肿样病变的免疫组化分析显示上皮细胞中 calretinin（-），基质细胞中 CD10（+），提示腹股沟皮下子宫内膜异位症伴疝囊。
患者随访 1 年无复发。
伴疝囊的皮肤子宫内膜异位症可无典型的子宫内膜异位症相关症状（如痛经）出现。腹股沟子宫内膜异位症可能是腹股沟无痛性结节的鉴别诊断。
