A recently observed case of deep infiltrating endometriosis with its vaginal invasion diagnosed by vaginal cytology is reported. A 28-year-old Japanese woman complained of a severe dysmenorrhea. Left ovarian endometriotic cyst and deep infiltrating endometriosis were suspected. Two red-spots were also present in the posterior fornix of vagina. Vaginal cytology with cytokeratin (CK) 7-immunocytochemistry suggested the presence of infiltrating endometriosis. She underwent left ovarian cystectomy and resection of thickened uterosacral ligaments with vaginal endometriotic spots, under a laparoscope, based on the diagnosis of endometriotic cyst. Histopathology revealed DIE with vaginal invasion. Immunostaining for CK7 was positive for endometriotic cyst, while CK20 was negative. The stromal cells in endometriosis were immunohistochemically positive for CD10. The vaginal fornix was well-healed one month later the surgery. Postoperatively, she got pregnant with her natural intercourse and delivered a healthy 2138 g girl at 36 weeks of gestation.
