Differential Diagnosis for White Vaginal Discharge in a Newborn
Single Most Likely Diagnosis
- Physiologic leukorrhea: This condition is a common and normal finding in newborns, caused by the exposure to maternal estrogen in utero, leading to vaginal discharge. It typically resolves on its own within the first few weeks of life.
Other Likely Diagnoses
- Vaginal yeast infection: Although less common in newborns, a yeast infection can cause a white, cottage cheese-like discharge. This might be more likely if the newborn has been exposed to antibiotics or has a compromised immune system.
- Bacterial vaginosis: This condition can also present with an abnormal vaginal discharge, though it's less common in newborns. The discharge might be white or gray and have a strong odor.
Do Not Miss Diagnoses
- Sexual abuse: Although extremely rare and unfortunate, any abnormal genital findings in a newborn should prompt a thorough investigation for potential sexual abuse. This includes any unusual discharge, bleeding, or physical trauma.
- Congenital infections (e.g., gonorrhea, chlamydia): These infections can be transmitted from mother to child during birth and may present with abnormal vaginal discharge. Prompt diagnosis and treatment are crucial to prevent long-term complications.
Rare Diagnoses
- Vaginal foreign body: The presence of a foreign object in the vagina can cause an abnormal discharge. This is rare in newborns but could potentially occur if an object was inserted during or after birth.
- Congenital vaginal anomalies: Certain congenital conditions, such as a vaginal septum or imperforate hymen, can lead to abnormal vaginal discharge. These conditions are rare and may require surgical intervention.
