Trichoscopy in trichotillomania: a useful diagnostic tool

Area of Science:

• Dermatology
• Trichology

Background:

• Trichotillomania (TTM) is a disorder characterized by compulsive hair pulling, leading to patchy alopecia.
• Diagnosis can be challenging, as differentiating TTM from other non-scarring alopecias requires careful evaluation.

Purpose of the Study:

• To investigate trichoscopic patterns in patients with suspected Trichotillomania.
• To evaluate the diagnostic significance of observed trichoscopic features in TTM.

Main Methods:

• A study involving ten patients with clinically suspected TTM was conducted.
• Dermoscopy was used to capture hair and scalp images.
• Histopathological examination was performed to confirm the diagnosis.

Main Results:

• The most common symptom was frontal patchy hair loss.
• Key trichoscopic findings included decreased hair density and broken hairs.
• Specific signs like black dots, flame hair, v-sign, and follicular hemorrhages were observed, alongside trichoptilosis and irregular coiled hairs.

Conclusions:

• Trichoscopy is a valuable tool for diagnosing Trichotillomania by identifying characteristic hair patterns.
• Early diagnosis through trichoscopy is crucial for timely and effective treatment of TTM.
