Which statement best describes intertriginous dermatitis?

1. Can only be caused by fungal infections

2. Results from dry skin and abrasion

3. Is due to trapped moisture and fold friction

4. Is rarely complicated by bacterial infections

The correct answer is: Is due to trapped moisture and fold friction

Intertriginous dermatitis is characterized by inflammation occurring in skin folds where moisture can become trapped, often exacerbated by friction between the skin surfaces. This condition typically arises in areas such as the axillae, groin, and under the breasts, where skin rubs together, creating an environment conducive to irritation and inflammation. The trapped moisture from sweat or other sources leads to maceration of the skin, which can further damage the skin barrier and allow for irritation. The other statements do not accurately reflect the condition. The assertion that intertriginous dermatitis can only be caused by fungal infections is misleading, as while fungal infections can be a factor, the condition can also arise from a combination of moisture, friction, and other irritants. The claim that it results from dry skin and abrasion overlooks the key role of moisture and friction in its development. Lastly, the indication that it is rarely complicated by bacterial infections fails to recognize that secondary bacterial infections are common complications due to the compromised skin barrier created by the dermatitis. Thus, the specifics of moisture and friction encapsulated in the correct answer provide a comprehensive understanding of the condition.
