A prospective study of tinea capitis in children: making the diagnosis easier with a dermoscope
Abstract Introduction Tinea capitis is a scalp infection caused by different fungi. Etiological diagnosis is based on suggestive clinical findings and confirmation depends on the fungus growth in culture. However, it is not always possible to perform this test due to lack of availability. The associ...
