We report 16 cases of trichilemmal pilar tumors. All of the patients were women of older ages. These unusual tumors are located chiefly on the scalp and consists of areas of squamous epithelium with non-epidermal keratinization and moderate cellular polymorphism. The origin of the tumor appears to be the outer root sheath of hair. Two of our cases were cystic. In order to avoid an erroneous diagnosis of squamous cell carcinoma, an adequate knowledge of these tumors is necessary.
我们报告了16例毛鞘瘤。所有患者均为老年女性。这些不常见的肿瘤主要位于头皮，由具有非表皮角化和中度细胞多形性的鳞状上皮区域组成。肿瘤起源似乎是毛外根鞘。我们的病例中有两例为囊性。为避免误诊为鳞状细胞癌，有必要充分了解这些肿瘤。
