The dye took some minutes to reach the ovary that showed a faint blue color of the cortex beneath the tunica albuginea (D). Photo E shows an endometriosis lesion within a lymphatic vessel of the lateral abdominal wall (the inset at the lower right corner shows a higher magnification thereof) as demonstrated at immunohistochemistry. Two endometriosis foci deeply invaded the peritoneum that lined the right diaphragm (F).","source_license":"CC0","license_restricted":false}
