Background:
Tinea pedis and tinea manuum in children are more common than previously recognized. Clinical presentations of dermatophyte infections may vary in children and may be difficult to diagnose.
Objective:
To show the necessity of potassium hydroxide preparations and/or fungal cultures in assessing suspicious cases of cellulitis in children who may have dermatophyte infections.
Patients:
We describe 4 children with inflammatory tinea pedis or tinea manuum who were initially misdiagnosed as having bacterial cellulitis.
Intervention:
A potassium hydroxide examination was performed on 3 patients. Fungal cultures were performed on 2 patients.
Results:
Inflammatory/bullous dermatophyte infections were detected by potassium hydroxide examination in all 4 patients and all 4 children successfully responded to topical antifungal therapy.
Conclusions:
These cases demonstrate that inflammatory tinnea pedis/manuum can masquerade as cellulitis in children. Early potassium hydroxide examination can allow appropriate antifungal treatment to be initiated before fungal culture results are finalized.
Insights
Pediatric fungal infections like tinea pedis and tinea manuum can mimic bacterial cellulitis. Prompt potassium hydroxide (KOH) examination is crucial for accurate diagnosis and effective antifungal treatment in children.
Area of Science:
- Pediatric Dermatology
- Mycology
Background:
- Tinea pedis and tinea manuum are increasingly recognized in children.
- Clinical presentations can be atypical and challenging to diagnose.
Purpose of the Study:
- To highlight the importance of potassium hydroxide (KOH) preparations and fungal cultures in diagnosing suspected dermatophyte infections presenting as cellulitis in children.
Main Methods:
- Case series of 4 children with inflammatory tinea pedis or tinea manuum initially misdiagnosed as bacterial cellulitis.
- Diagnostic methods included KOH examination (3 patients) and fungal cultures (2 patients).
Main Results:
- KOH examination confirmed inflammatory/bullous dermatophyte infections in all 4 patients.
- All children achieved successful outcomes with topical antifungal therapy.
Conclusions:
- Inflammatory tinea pedis/manuum can be misdiagnosed as cellulitis in pediatric cases.
- Early KOH examination facilitates timely antifungal treatment, even before definitive fungal culture results.
