Congenital triangular alopecia (CTA) is a form of circumscribed, noncicatricial, and noninflammatory hair loss. It manifests as a triangular or oval-shaped alopecic patch on the frontotemporal region of the scalp and rarely involves the temporoparietal or occipital area. That is why it is also called temporal triangular alopecia. However, there has been just one case reported in the middle frontal area. Here, we report a successfully treated case of CTA in a 17-year-old boy who was born with a 2.5 cm × 3.5 cm alopecic patch in the middle frontal area.
先天性三角形秃发(CTA)是一种局限性、非瘢痕性、非炎症性脱发。它表现为头皮额颞部的三角形或椭圆形脱发区,很少累及颞顶或枕部区域。这就是它也被称为颞部三角形秃发的原因。然而,仅在额中部区域报道过1例。在此,我们报告1例成功治疗的先天性三角形秃发病例,患者为一名17岁男孩,出生时额中部有一块2.5厘米×3.5厘米的脱发区。
