Background: There are various causes of non-scarring alopecia in the pediatric population. Temporal triangular alopecia is a rare condition that may be easily misdiagnosed without careful history and examination.
Case Presentation: We present a case of asymptomatic hair loss in a pediatric patient and a review of non-scarring causes of alopecia commonly seen in the primary care setting. The patient denied known trauma, life stressors, or hair pulling. Clinical findings included a focal triangular-shaped patch of non-scarring alopecia involving the frontotemporal scalp. He was found to have temporal triangular alopecia and was counseled regarding its nonprogressive nature and poor prognosis for hair regrowth.
Conclusion: We believe this case to be relevant to primary care providers and other clinicians in the diagnosis and management of an uncommon cause of alopecia in the pediatric population.
