Medical Terminology for Yeast Rash on Abdominal Folds
The medical term for a yeast rash on abdominal folds is "candidal intertrigo" or "intertriginous candidiasis." 1, 2
Definition and Clinical Presentation
Intertrigo is a superficial inflammatory dermatitis occurring on two closely opposed skin surfaces caused by moisture, friction, and lack of ventilation. 2 When this becomes secondarily infected with Candida species (yeast), it is specifically termed candidal intertrigo. 2
Key Clinical Features
- Physical examination reveals regions of erythema with peripheral scaling in skin fold areas 2
- Satellite lesions are the characteristic diagnostic feature that distinguishes candidal intertrigo from simple intertrigo 2
- The condition commonly affects natural body folds and obesity-created folds, including abdominal folds 3
- Bodily secretions including perspiration often exacerbate the skin inflammation 2
Diagnostic Approach
- Candidal intertrigo is commonly diagnosed clinically based on the characteristic appearance of satellite lesions 2
- Diagnosis may be confirmed using a potassium hydroxide (KOH) preparation if clinical diagnosis is uncertain 2
- In treatment-resistant or recurrent cases, laboratory studies ranging from simple tests to advanced methods should be performed to establish a differential diagnosis 4
Important Clinical Context
- This represents a secondary fungal infection that develops when excessive friction and inflammation cause skin breakdown, creating an entry point for Candida organisms 2
- The condition is strongly associated with obesity, as increased skin folds create environments conducive to moisture accumulation and fungal overgrowth 5
- Candida species are part of normal endogenous flora in 40-50% of humans but can cause infection when local conditions favor overgrowth 6
