Intertrigo and secondary skin infections.
Intertrigo is a superficial inflammatory dermatitis occurring on two closely opposed skin surfaces as a result of moisture, friction, and lack of ventilation. Bodily secretions, including perspiration, urine, and feces, often exacerbate skin inflammation. Physical examination of skin folds reveals regions of erythema with peripheral scaling. Excessive friction and inflammation can cause skin breakdown and create an entry point for secondary fungal and bacterial infections, such as Candida, group A beta-hemolytic streptococcus, and Corynebacterium minutissimum. Candidal intertrigo is commonly diagnosed clinically, based on the characteristic appearance of satellite lesions. Diagnosis may be confirmed using a potassium hydroxide preparation. Resistant cases require oral fluconazole therapy. Bacterial superinfections may be identified with bacterial culture or Wood lamp examination. Fungal lesions are treated with topical nystatin, clotrimazole, ketoconazole, oxiconazole, or econazole. Secondary streptococcal infections are treated with topical mupirocin or oral penicillin. Corynebacterium infections are treated with oral erythromycin.
