Medical Term for Yeast Infection Under Armpits
The medical term for a yeast infection of the armpit is "Candida intertrigo" or "candidal intertrigo." 1
Understanding the Terminology
Candida intertrigo specifically refers to a yeast infection caused by Candida species (most commonly C. albicans) that occurs in intertriginous areas—the body's skin folds including the axillae (armpits), groin, under breasts, and other flexural areas 2, 1.
Why This Location is Susceptible
The axillae are particularly vulnerable to fungal infections because they are:
- Underventilated and moist environments
- Exposed to friction from arm movement
- Warm areas that create ideal conditions for yeast proliferation 2
Clinical Recognition
Physical examination is the primary diagnostic approach for mucocutaneous candidiasis like Candida intertrigo 3. The diagnosis is confirmed by:
- Observing mycelial forms on microscopic examination
- Clinical appearance of the affected area
- Important caveat: Positive culture alone does not confirm infection, as Candida species are normal skin inhabitants—you must see tissue invasion or clinical signs 1
Predisposing Factors to Consider
Since Candida has relatively low pathogenicity, look for:
- Disturbances in the cutaneous microenvironment (moisture, occlusion)
- Local immunosuppression
- Systemic immunosuppression
- Recurrent infections suggest underlying predisposing factors that need evaluation 1
