TLDR Trichoscopic examination is crucial for diagnosing congenital triangular alopecia.

The document described a case of congenital triangular alopecia (CTA), a rare, non-inflammatory, and non-scarring form of alopecia, in a 9-month-old boy. CTA typically presents as a triangular, ovoid, or lancet-shaped patch of hair loss in the frontotemporal region of the scalp, appearing at birth or within the first 9 years of life. The case highlighted the use of trichoscopic examination for diagnosis, as the condition did not respond to topical steroids and traditional treatments. The study aimed to emphasize the diagnostic process using a dermatoscope and discussed potential treatment approaches for CTA.
