Differential Diagnosis for Cuts Along Sides of Tongue in a 6-Month-Old
- Single Most Likely Diagnosis
- Oral thrush with traumatic tongue lacerations: This is a common condition in infants, characterized by a fungal infection that can cause white patches on the tongue and mucous membranes. The cuts along the sides of the tongue could be due to the infant's tongue moving against the sharp edges of teeth or other oral structures, exacerbated by the discomfort of thrush.
- Other Likely Diagnoses
- Accidental trauma: Infants at this age are beginning to explore their environment and may accidentally bite their tongue or get it caught, leading to cuts.
- Teething: As teeth start to erupt, the process can cause irritation and accidental biting of the tongue, leading to cuts.
- Tongue-tie (ankyloglossia): Although not typically associated with cuts, a severe tongue-tie could potentially cause the tongue to move abnormally and lead to trauma against the teeth.
- Do Not Miss Diagnoses
- Child abuse: Although unlikely, any unexplained injury in an infant must prompt consideration of non-accidental trauma. It's crucial to investigate the circumstances surrounding the injury.
- Infection or abscess: A bacterial or fungal infection could lead to severe inflammation and potentially life-threatening complications if not addressed promptly.
- Rare Diagnoses
- Stomatitis: An inflammation of the mucous lining of the mouth, which could be caused by various factors including infection, allergy, or autoimmune disorders.
- Erythema multiforme: A rare skin condition that can affect the mucous membranes, including the tongue, and is characterized by target-like lesions.
- Autoimmune disorders: Such as pemphigus or pemphigoid, which are rare in infants but could cause blistering lesions that might appear as cuts.
