2. Figure 1
Photomicrographs showing histologic patterns of endometriosis. (A) Stromal cells characterized by the presence of endometrial stroma similar to those at any stage of the menstrual cycle. (B) Endometriosis of well-differentiated gland epithelial cells with ectopic morphology indistinguishable from the corresponding stages of the menstrual cycle (C) Undifferentiated endometriosis showing a low cuboidal epithelium without endometria corresponding to the lining of the peritoneal mesothelium. (D) Mixed endometriosis showing cells with different patterns (E) and levels of undifferentiation (F). Original magnification, ×400 in A and B, ×200 in C–E. All panels, hematoxylin and eosin stain.
