Differential Diagnosis for Candidiasis in an Infant's Neck
- Single Most Likely Diagnosis
- Thrush: This is the most common cause of candidiasis in infants, often presenting as white patches on the mucous membranes of the mouth, but can also spread to the neck area, especially if the infant has been touching their mouth and then their neck.
- Other Likely Diagnoses
- Cutaneous Candidiasis: This condition can occur in warm, moist areas of the body, including the neck, especially in infants who wear tight clothing or have skin folds that trap moisture.
- Intertrigo: A type of skin infection that occurs in skin folds, caused by Candida, which can be seen in the neck area of infants, particularly if they have excessive sweating or use of occlusive dressings.
- Do Not Miss Diagnoses
- Congenital Syphilis: Although less common, congenital syphilis can cause skin rashes, including in the neck area, and is critical to diagnose early due to its severe consequences if left untreated.
- Impetigo: A highly contagious skin infection that can present with red sores on the face and neck, which, although not typically caused by Candida, is crucial to identify due to its contagious nature and potential for complications.
- Rare Diagnoses
- Histoplasmosis: A fungal infection that can cause skin lesions, although it's more commonly associated with lung infections. It's rare but could be considered in endemic areas or in cases where typical treatments for candidiasis are not effective.
- Blastomycosis: Another rare fungal infection that can cause skin lesions, among other symptoms. It's less likely but should be considered in differential diagnosis, especially in regions where the fungus is common.
