Sensitivity of CD10 in pelvic endometriosis was determined to be 88% (22/25) [37], or 95.83% (46/48) [38] or 85% (17/20) [39] in endometriosis cases, but all sections from lesions that may simulate endometriosis like for example endosalpingiosis were CD10 negative [39]. Here, MME is linked to endometriosis.
