The differential diagnosis for pediatric prepubertal vaginal bleeding is wide. Rare etiologies include vascular malformations and tumors, such as infantile hemangiomas (IHs), which validate the usefulness of exam under anesthesia, vaginoscopy, and tissue diagnosis.
We report a case of an IH in a 6-year-old girl causing vaginal bleeding requiring transfusion. Vaginoscopy revealed a cervical IH of less than 1 cm. Expectant management and oral propranolol were successful management options.
Rare, even small soft tissue tumors such as IH can lead to impressive blood loss via vaginal bleeding. Accurate tissue diagnosis and a multidisciplinary approach are essential to planning safe, effective treatment, and follow-up.
青春期前小儿阴道出血的鉴别诊断范围广泛。罕见病因包括血管畸形和肿瘤，如婴儿血管瘤（IHs），这证实了在麻醉下检查、阴道镜检查和组织诊断的实用性。
我们报告一例6岁女孩的婴儿血管瘤导致阴道出血需输血的病例。阴道镜检查发现宫颈婴儿血管瘤小于1厘米。观察性处理和口服普萘洛尔是成功的处理方法。
罕见的，即使是小的软组织肿瘤如婴儿血管瘤也可通过阴道出血导致大量失血。准确的组织诊断和多学科方法对于规划安全、有效的治疗及随访至关重要。
