Patients with intertrigo typically have erythematous ("beefy red") plaques in a symmetric "kissing" or "mirror image" pattern across the skinfold and multiple satellite lesions near the primary infection.

The most common cause of intertrigo is Candida albicans, a part of the normal flora of the urogenital and gastrointestinal tracts.  Patients at risk for candida intertrigo include those with impaired immunity (eg, systemic corticosteroid use, diabetes mellitus), particularly when associated with increased skin moisture or friction (eg, obesity, tight-fitting clothing), which can cause skin maceration and trauma.

Diagnosis is typically clinical but can be confirmed by visualization of hyphae or pseudohyphae on microscopic examination of skin scrapings from affected areas.

Treatment is typically with topical azoles (eg, clotrimazole, ketoconazole), which help decrease the spread of infection and have some anti-inflammatory and antibacterial properties.
