Trichoscopic Evaluation of Tinea Capitis

Area of Science:

• Dermatology
• Mycology
• Medical Diagnostics

Background:

• Tinea capitis (TC) is a common fungal infection, especially in children in rural areas.
• Conventional diagnostic methods like KOH microscopy, Wood's lamp, and fungal culture have limitations including low sensitivity and long turnaround times.
• Trichoscopy offers a practical and beneficial approach to diagnosing scalp and hair disorders.

Purpose of the Study:

• To evaluate the utility of trichoscopy in the diagnosis of tinea capitis.
• To identify characteristic trichoscopic findings associated with non-inflammatory tinea capitis.
• To assess the potential of trichoscopy in guiding treatment and monitoring response.

Main Methods:

• Review of studies over the past 15 years focusing on trichoscopic findings in tinea capitis.
• Identification of specific trichoscopic features such as comma hairs, corkscrew hairs, Morse code-like hairs, and zigzag hairs.
• Comparison of trichoscopy with conventional diagnostic methods.

Main Results:

• Trichoscopy reveals characteristic findings in non-inflammatory tinea capitis, including comma, corkscrew, Morse code-like, and zigzag hairs.
• These findings facilitate prompt diagnosis of TC.
• Trichoscopy enables identification of the responsible dermatophyte, allowing for timely and appropriate treatment.

Conclusions:

• Trichoscopy is an effective tool for the rapid diagnosis of tinea capitis.
• It aids in identifying the causative fungus and monitoring treatment response by observing the clearance of specific trichoscopic features.
• This method improves patient management by enabling prompt diagnosis and timely intervention for fungal scalp infections.
