Temporal Triangular Alopecia-Clinical and Dermoscopic Features of a Rare Entity

Area of Science:

• Dermatology
• Trichology

Background:

• Temporal triangular alopecia (TTA) is a congenital, non-scarring form of hair loss.
• It typically presents as a triangular patch of reduced hair density in the temporal region.

Purpose of the Study:

• To present a case of temporal triangular alopecia (TTA).
• To discuss the clinical and trichoscopic diagnostic features of TTA.
• To highlight the management approach for TTA.

Main Methods:

• Case report of an 18-year-old female patient.
• Clinical examination for hair loss assessment.
• Trichoscopic evaluation of the affected scalp region.

Main Results:

• A diagnosis of temporal triangular alopecia (TTA) was confirmed based on clinical and trichoscopic findings.
• The condition was congenital, non-progressive, and asymptomatic.
• No treatment was initiated as it did not affect the patient's quality of life.

Conclusions:

• Temporal triangular alopecia (TTA) is a benign condition.
• Diagnosis relies on characteristic clinical and trichoscopic features.
• Management is conservative, focusing on patient reassurance and monitoring, especially when asymptomatic.
