Which dermatological condition is characterized by inflammation under pendulous breasts with discharge?

The dermatological condition characterized by inflammation under pendulous breasts with discharge is intertrigo. This condition occurs in skin folds where moisture, friction, and heat can create an environment conducive for inflammation. Under pendulous breasts, the skin can rub against itself and trap moisture, leading to irritation and potential infection, which may manifest as redness and discharge.

Intertrigo primarily affects skin folds such as those found under the breasts, in the groin, and between the toes. It can involve secondary infections, often due to the growth of yeast or bacteria in the warm, moist areas. This makes it distinct from other skin conditions that may not specifically relate to such locations or have similar etiology.

The other options represent different skin conditions but do not encapsulate the unique characteristics of intertrigo, especially in the context of pendulous breasts and associated discharge. For example, contact dermatitis primarily arises from an allergic reaction or irritation due to substances in contact with the skin rather than being associated with skin folds. Psoriasis involves raised, scaly patches that persist and are not specifically related to body folds or discharge. Eczema is characterized by itchiness and inflammation but typically does not include the specific characteristics seen in intertrigo, particularly in the breast area.
