TLDR A 3-year-old boy was diagnosed with a rare, non-scarring hair loss condition called temporal triangular alopecia.
Temporal triangular alopecia (TTA) is a rare, non-scarring form of hair loss characterized by an alopecic patch in the frontotemporal region, which can be present at birth or develop early in life. The condition's etiology is unknown, and it is diagnosed based on clinical and dermoscopic examination. Differential diagnoses include alopecia areata, trichotillomania, tractional alopecia, and congenital aplasia cutis. Misdiagnosis and unnecessary treatments are common due to its rarity. The document presented a case report of a 3-year-old boy diagnosed with TTA.
