title: Histologic classification of specimens from women affected by superficial endometriosis, deeply infiltrating endometriosis, and ovarian endometriomas.
abstract: In this retrospective observational study involving 176 patients and 271 biopsies, the histologic differentiation in superficial endometriosis, deeply infiltrating endometriosis, and ovarian endometriomas was evaluated according to a previously proposed classification system. Results showed a predominance of the undifferentiated glandular pattern (33.5%) and mixed glandular pattern (46.9%) in deeply infiltrating endometriosis lesions, whereas the well-differentiated glandular pattern (41.8%) was most frequently seen in superficial endometriosis lesions, and in ovarian endometriomas a predominance of both the undifferentiated (40.5%) and mixed patterns (37.8%) was observed.
