- LCH of the female reproductive tract has four patterns of involvement.
- A comprehensive literature review revealed 35 cases of pure genital LCH.
- We report two new cases of pure LCH lesions of the vulva and one of the cervix.
- Treatment of LCH varies and there is no standard for pure genital involvement.
- Prognosis of LCH confined to the gynecologic tract appears to be favorable.
