Intertrigo is an inflammatory condition of opposing skin surfaces, driven by friction, heat and moisture that weaken the skin barrier and invite secondary infections, especially Candida and bacteria. It affects all ages, from infants with diaper dermatitis to older adults with limited mobility. It is more common in hot climates and in patients with obesity or diabetes. Clinically, it presents with symmetrical erythema that may progress to maceration, fissures, discharge and secondary infection. The diagnosis is mainly clinical, with cultures or potassium hydroxide testing when needed. Management focuses on reducing moisture and friction, treating infections and using gentle barrier protection. In this episode, Dr Roger Henderson looks at how to identify and manage this condition, which is commonly seen in primary care.
