We describe a 10-year-old female patient who presented with vulvar swelling for 23 days. She has no history of sexual assault and irradiation. Two months ago, the patient underwent CO2 laser surgery for a sebaceous gland nevus on the left labia majora, resulting in delayed healing and residual scar tissue. Twenty-three days ago, swelling appeared in the external genitalia, accompanied by mild pain that worsened after activity and lessened when lying down. Treatment with anti-infection and anti-allergy medications at the previous hospital did not show significant improvement. Histopathological examination and genetic testing confirmed Our diagnosis of acquired vulvar lymphangioma with lymphedema.Keywords: acquired vulvar lymphangiectasia, lymphangioma, lymphedema
