Lipschütz ulcer (LU) is an uncommon condition that usually affects prepubertal and pubertal girls. It can be misdiagnosed as a sexually transmitted disease or even as a sign of child abuse, causing great anxiety to patients and their families. We present two cases of LU consecutively affecting twin sisters. To our knowledge, this is the first case in two family members, supporting infectious transmission. We propose airborne transmission as the most probable cause in our cases.
