Seborrhoeic dermatitis-like tinea faciei in an infant
Insights
Facial fungal infections in infants can mimic seborrhoeic dermatitis. Early diagnosis through mycological examination is crucial for identifying tinea faciei caused by dermatophytes like Trichophyton mentagrophytes.
Area of Science:
- Dermatology
- Mycology
- Pediatrics
Background:
- A 6-month-old infant presented with a 4-month history of facial erythema and scaling.
- Initial clinical suspicion was seborrhoeic dermatitis due to lesion characteristics and infant age.
Discussion:
- Microscopic examination revealed septate hyphae, and fungal culture confirmed a dermatophyte infection.
- The identified species was Trichophyton mentagrophytes, a common cause of fungal infections.
Key Insights:
- This case underscores the importance of considering tinea faciei in infants with facial rashes.
- Seborrhoeic dermatitis is a common differential diagnosis, but fungal infections require specific treatment.
Outlook:
- Emphasizes the diagnostic value of prompt mycological examination for facial eruptions in infants.
- Highlights the need for increased awareness of pediatric tinea faciei among clinicians.
Abstract:
The patient we present herein is a 6-month-old infant who had erythema and scaling on the central part of the face for 4 months. Both the abundant scaling and the localisation, but also the low age of this infant led to suspect seborrhoeic dermatitis. Direct microscopic examination of scales showed septate hyphae and the cultural examination was also positive for dermatophyte. The found species was Trichophyton mentagrophytes. We describe this patient to highlight the importance of considering tinea faciei in the differential diagnosis of all facial eruptions and the value of mycological examination.
