The biopsy taking during laparoscopy shows cysts lined with cubic to cylindrical epithelium. Endometrial stroma is absent (a, 11× magnification). High power magnifications (b: 100×, c: 400×) reveal that the well-differentiated epithelium has cilia, much like fallopian tubes epithelium (Black boxes: magnified areas).
