定义
外毛根鞘囊肿是一种常见的、典型的非压痛性皮内或皮下囊肿。囊肿通常局限于头皮,且多发。它们通常偶发,但可能以常染色体显性方式遗传。它们来源于毛囊的外根鞘,因此含有角蛋白或角蛋白降解产物。他们很少发生恶性转化。
A trichilemmal (pilar) cyst is a common, typically non-tender, intradermal or subcutaneous cyst. The cysts are typically confined to the scalp and are often multiple. They usually occur sporadically but may be inherited in an autosomal dominant manner. They are derived from the outer root sheath of the hair follicle and as such contain keratin or keratin degradation products. Rarely, they may undergo malignant transformation.
