Differential Diagnosis for Intertrigo vs Candida Infection vs Cellulitis
Single Most Likely Diagnosis
- Intertrigo: This is the most likely diagnosis given the presentation of skin folds and warm, moist environments that are prone to friction and maceration, which are ideal conditions for intertrigo to develop. Intertrigo is a type of skin inflammation caused by skin-on-skin friction, typically occurring in skin folds.
Other Likely Diagnoses
- Candida Infection: Candida thrives in warm, moist areas, making it a common cause of infections in skin folds. Symptoms can overlap with intertrigo, including redness, itching, and a burning sensation.
- Cellulitis: This is a bacterial skin infection that can occur when bacteria enter through a crack or break in the skin. It presents with redness, swelling, and warmth, which can be similar to the presentation of intertrigo and candida infections, especially if the skin barrier is compromised.
Do Not Miss Diagnoses
- Necrotizing Fasciitis: Although rare, this is a life-threatening condition that can arise from bacterial infections, including those causing cellulitis. It requires immediate medical attention and can present with severe pain, swelling, and skin necrosis.
- Erysipelas: A type of bacterial infection involving the upper dermis, typically caused by Streptococcus bacteria. It presents with well-demarcated, raised, and shiny lesions and can be mistaken for cellulitis or other skin infections.
Rare Diagnoses
- Dermatophyte Infections: Fungal infections caused by dermatophytes can occur in skin folds and might be considered in the differential, especially if the patient has not responded to typical treatments for intertrigo or candida.
- Erythrasma: A bacterial infection caused by Corynebacterium minutissimum, which thrives in warm, moist areas. It presents with well-demarcated, brownish-red patches and can be mistaken for other skin fold infections.
