Intertrigo, also known as intertrigo, is an acute superficial inflammation characterized by erythema and erosion that occurs in the folds of the skin.

bubble_chart Etiology

The condition occurs because sweat accumulates in skin folds, making the stratum corneum prone to softening, and frequent friction with the opposite skin further contributes to its development.

bubble_chart Clinical Manifestations

This disease is commonly seen in dampness-heat seasons and frequently occurs in infants and obese adults.

Moist, bright red, or dark red patches appear in the skin folds of the neck, armpits, groin, gluteal cleft, flexural surfaces of limb joints, and under the breasts in women. The affected area corresponds to the skin folds that rub against each other. Patients may experience itching or burning pain. The affected area shows grade I swelling, with macerated and whitened epidermis that may peel off, leaving an eroded surface exuding serous fluid. Due to the decomposition of serous fluid and bacterial growth, a foul odor may be emitted. If secondary Candida infection occurs, scattered papules and blisters may appear around the area. If secondary bacterial infection occurs, purulent discharge may be present.

bubble_chart Diagnosis

It is easy to diagnose based on the characteristics of erythema and erosion in the folds during the mixed heat season.

bubble_chart Treatment Measures

Skin folds should be cleaned frequently and kept dry and clean, or dusted with powder to reduce sweat soaking and friction. In the erythema stage, only powder is needed. For erosions, apply 40% zinc oxide oil or use a 3% boric acid solution for wet compresses. If there is bacterial infection, wash with a 0.5% Coptis Rhizome solution; for Candida infection, use powder containing nystatin or other antifungal medications.
