Loose anagen hair syndrome is an uncommon hair disorder, particularly in non-Caucasian children. We report the case of a 13-year-old Thai boy who presented with a single patch of hair thinning on the frontal scalp with excessive shedding, and the hairs did not grow long. Microscopic examination showed naked anagen bulbs with ruffling of the cuticle, which is compatible with loose anagen hair syndrome. To our knowledge, there is no reported case in Southeast Asian children.
生长期松动综合征是一种罕见的毛发疾病，在非白种人儿童中尤为少见。我们报告一例13岁泰国男孩的病例，其额部头皮出现单发的片状头发稀疏并伴有过度脱落，头发无法长长。显微镜检查显示毛干呈裸生长期毛囊球，伴有角质层皱缩，符合生长期松动综合征。据我们所知，东南亚儿童中尚无此类病例报道。
