Acta Dermato-Venereologica
|January 1, 1975
Summary
White piedra, a fungal infection, was diagnosed in a Finnish male presenting with scrotal hair nodules. Trichosporum cutanum was identified as the causative agent, confirming the rare condition in a non-endemic region.
Area of Science:
- Dermatology
- Mycology
- Infectious Diseases
Background:
- Piedra is a superficial fungal infection affecting hair shafts.
- White piedra is characterized by white or cream-colored nodules on hair.
- Trichosporum cutaneum (T. beigelii) is the common etiological agent of white piedra.
Purpose of the Study:
- To report a rare case of white piedra diagnosed in a Finnish male.
- To highlight the clinical presentation and etiological agent of white piedra.
Main Methods:
- Clinical examination of scrotal hair for nodules.
- Fungal culture for etiological identification.
Main Results:
- Brownish-black nodules were observed on the scrotal hair shafts.
- Fungal culture confirmed the presence of Trichosporum cutaneum (T. beigelii).
- Diagnosis of white piedra was established.
Conclusions:
- White piedra can occur in geographical regions where it is not commonly reported.
- Trichosporum cutaneum is the causative agent of white piedra, even in atypical presentations.
- Early clinical suspicion and mycological examination are crucial for accurate diagnosis.
