Intertrigo

Intertrigo

Intertrigo is a skin disorder caused by the macerating effects of heat, moisture and friction. Most often seen in the groin, axillae or in inframammary folds (1).

Aetiological factors include:

• past history of seborrhoeic dermatitis
• infection with Candida albicans
• diabetes mellitus
• obesity
• poor hygiene
• humid climate

Characteristically intertigo presents as mild erythema which can be seen initially as red plaques on each side of the affected skin fold (in a mirror image fashion). The patient complains of itching, stinging and burning (1). As the erythema progresses features of a more intense inflammation may develop e.g. - erosions, oozing, fissures, exudation, maceration, and crusting (1).

The moist and damaged skin predisposes to secondary skin infections (1).

Examination reveals red, weeping skin at the site of moist skin folds.

Treatment includes:

• drying the skin with talcum powder
• patients should use light, absorbent cloths and keep away from nylon or other synthetic fabrics
• topical treatment with antifungals (which may be combined with a steroid cream) eg trimovate
• oral antibacterial or antifungal therapy may also be indicated (1).
