Woolly hair nevus is a rare entity characterized by structural anomaly, which presents as curly hair in a circumscribed area of scalp, in a nonNegroid individual. These are abnormal hairs which are short, thin, and sparse. The term "woolly hair" refers to tightly coiled hair covering the whole scalp or part of it and has a hereditary character. Trichotillomania is a chronic impulse control disorder, characterized by the repetitive pulling out of one's own hair, leading to noticeable hair loss. Here, we present the case of a 9-year-old male child with woolly hair nevus over the occipital area, which developed at the age of 3 years; later, he developed trichotillomania at the age of 5 years, adjacent to the nevus. According to the best of our knowledge, there is no case report of woolly hair nevus presenting with trichotillomania till date.
羊毛状发痣是一种罕见的以结构异常为特征的疾病，表现为非黑人个体头皮特定区域出现卷曲毛发。这些毛发异常短小、纤细且稀疏。“羊毛状发”指覆盖整个头皮或部分头皮的紧密卷曲毛发，具有遗传性。拔毛癖是一种慢性冲动控制障碍，其特征是反复拔除自己的毛发，导致明显脱发。在此，我们报告一例9岁男性患儿，枕部有羊毛状发痣，3岁时出现；5岁时，在痣旁出现了拔毛癖。据我们所知，迄今为止尚无羊毛状发痣伴发拔毛癖的病例报告。
