Studysummary This case report highlighted two atypical childhood alopecia cases: congenital atrichia without papules and Bjornstad syndrome with alopecia areata; emphasizing diagnostic challenges, notably the absence of keratotic papules usually associated with congenital atrichia and the presence of alopecia areata in Bjornstad syndrome.

This report describes two pediatric cases of atypical alopecia, highlighting the diagnostic role of trichoscopy. The first case involves a 4-year-old boy with congenital atrichia without papules, characterized by complete scalp hair loss shortly after birth, and the second case is a 6-year-old girl with Bjornstad syndrome and alopecia areata, featuring short, brittle hair and sensorineural hearing loss. Both conditions are rare genetic disorders with no specific treatments, emphasizing symptom management to improve quality of life. The study underscores the importance of trichoscopy in diagnosing these disorders, despite financial constraints limiting genetic analysis.
