A practical method to detect mycoses of the nails
Abstract:
The authors present a method that allows for reliable identification of fungal structures in nails with suspected colonization by fungi. The method is based on the well-known technique of heating nail fragments in 20% potassium hydroxide, but its details allow for reliable and quick processing of samples, when convenient. The method requires simple equipment and is designed for individual practices but might be employed as is or with minor technical improvements by a dermatology department. Minor changes will make it feasible to simultaneously process several samples. The results that were obtained show that while experienced clinicians achieve positive clinical diagnoses in the majority of instances, inaccuracies occur in a sizable proportion of cases. In addition, the varied combination of yeasts and hyphae that were found, bolster the view that microscopic examination is necessary to justify and optimize systemic treatment of mycoses of the nails. Our technique permits the processing and observation of the totality of samples obtained from a single nail or several nails.
Insights
This study introduces a reliable, quick method for identifying fungal nail infections using potassium hydroxide. Microscopic examination is crucial for accurate diagnosis and effective treatment of nail mycoses.
Area of Science:
- Dermatology
- Mycology

Purpose of the Study:
- To present a reliable and efficient method for identifying fungal structures in nail samples.
- To improve the accuracy of diagnosing nail fungal infections.
Main Methods:
- The method involves heating nail fragments in 20% potassium hydroxide (KOH).
- It utilizes simple equipment suitable for individual practices and can be adapted for high-volume processing.
Main Results:
- The technique allows for reliable and quick processing of nail samples.
- Microscopic examination revealed varied combinations of yeasts and hyphae, underscoring its diagnostic necessity.
- The study highlights inaccuracies in clinical diagnoses even by experienced practitioners.
Conclusions:
- Microscopic examination of nail samples is essential for accurate diagnosis and optimized treatment of onychomycosis.
- This method provides a practical approach for reliable fungal identification in nail specimens.
