The hair casts are infrequent condition. There are two distinct groups: idiopathic and secondary. Idiopathic hair casts are described in three girls aged 3, 5 and 13 years. They are cousins, indicating a possible hereditary influence. It's a illness without systemic affection, with pathophysiology yet unknown. It is important to know, overall for differential diagnosis, specially nits. The only treatment is removal of casts by careful and repeated combing.
毛发管型是一种罕见病症。它分为两个不同的类型：特发性和继发性。有三名年龄分别为3岁、5岁和13岁的女孩被描述为患有特发性毛发管型。她们是表亲，这表明可能存在遗传影响。这是一种无全身影响的疾病，其病理生理学尚不清楚。总体而言，了解这一点对于鉴别诊断很重要，尤其是与虱卵的鉴别。唯一的治疗方法是通过仔细反复梳理去除管型。
