A 45-year-old male with obesity complains of a persistent rash in his skin folds. Physical examination reveals erythematous, moist lesions with some areas of maceration in his skin folds. What could be the potential cause, and what are the next steps?
This patient's symptoms and physical findings suggest intertrigo, a common skin condition in individuals with obesity characterized by inflammation of skin folds due to friction, heat, and moisture. The diagnosis is typically clinical. Management involves keeping the area dry, topical antifungal or antibacterial creams if secondary infection is suspected, and potentially topical corticosteroids for inflammation. Weight loss would also be beneficial in preventing recurrence.
