We report here a 14-year-old girl with diffuse partial woolly hair. The patient presented mild hair loss associated with the presence of fine, short and kinky hairs closely interspersed with the normal hair throughout the scalp. The pathology of the scalp revealed the presence of intermediate-sized hair follicles regularly intermingled with normal follicles in each follicular unit. The possibility that diffuse partial woolly hair may result from a progressive miniaturization of the hair follicles may explain the presence of evident hair thinning in several adult patients affected by this rare abnormality.
我们在此报告一名患有弥漫性部分羊毛状毛发的14岁女孩。患者表现为轻度脱发，头皮各处有纤细、短小且卷曲的毛发与正常毛发紧密相间。头皮病理显示每个毛囊单位中存在中等大小的毛囊，与正常毛囊规则混合。弥漫性部分羊毛状毛发可能由毛囊进行性小型化导致，这一可能性或许可以解释几名患有这种罕见异常的成年患者明显的头发稀疏现象。
