Intertrigo

Excerpt

Intertrigo is a superficial inflammatory skin condition that affects flexural surfaces, such as the axillae, abdominal folds, and perineum. This condition is often triggered or aggravated by warm temperatures, friction, moisture, maceration, and poor ventilation. The Latin origins of the term "intertrigo"—inter (meaning "between") and terere (meaning "to rub")—illustrate the physiology of the condition. Intertrigo often becomes secondarily infected, particularly by Candida, although other viral or bacterial pathogens also contribute to its pathogenesis (see Image. Candida-Associated Intertrigo).

Intertrigo can occur at any age and is primarily diagnosed clinically; in more complex cases, further evaluation, such as culturing or skin scraping, may be needed to identify specific pathogens. Intertrigo typically presents as erythematous patches of varying intensity, which may progress to erosions and secondary lesions due to irritation or manipulation.
