Pediatric Nail Diseases: Clinical Pearls
Our dermatology department recently sponsored a pediatric dermatology lecture series for the pediatric residency program...
Conclusion
In this study, we investigated the benefit of successive KOH testing in the laboratory diagnosis of tinea pedis and found that the use of second samples in particular provided a substantial increase in diagnostic yield. In other words, the utilization of successive KOH testing remarkably improved the diagnosis of tinea pedis. Therefore, we suggest that at least 2 samples of skin scrapings should be taken for the diagnosis of tinea pedis and that the number of samples should be at least 3 for keratotic lesions. However, further study by using a gold-standard method such as a molecular-based assay as well as taking the samples in daily or weekly intervals is recommended to achieve a more reliable result.
