摘要： 目的：对毛母质瘤的皮肤镜特征进行总结，为提高毛母质瘤的临床诊断率提供一些线索。方法：收集分析行病理学检查及皮肤镜检查的毛母质瘤患者临床资料。结果：共收集10例毛母质瘤患者，其中男5例，女5例，年龄3~22岁。7例（70%）毛母质瘤位于头面部，2例（20%）位于上肢，1例（10%）位于肩颈部。初步临床诊断包括毛母质瘤、皮肤肿物、瘢痕疙瘩、化脓性肉芽肿、表皮囊肿、传染性软疣、皮脂腺增生、Spitz痣，临床诊断符合率仅为20%。毛母质瘤最常见的皮肤镜特征包括黄白色无结构区（90%）、紫红色均质区域（80%）、不规则分枝状血管（60%）及白色条纹（60%）。结论：毛母质瘤初步诊断误诊率高，皮肤镜常见表现为黄白色无结构区、紫红色均质区域、不规则分枝状血管及白色条纹等。

Abstract: Objective: To analyze dermoscopic features in 10 cases of pilomatricoma and offer some help for diagnosis. Methods: The data of 10 patients with pilomatricoma who undergoing the dermoscopic examination and pathological examination were analyzed. Results: A total of 10 patients were collected, including 5 males and 5 females, ageing from 3-22. The lesions were located on the head and face in seven cases (70%), on the upper limbs two cases (20%) , and on the neck in one case (10%). The preliminary clinical diagnosis included piloblastoma, skin neoplasms, keloid, granuloma pyogenicum, epidermal cyst, molluscum contagiosum, sebaceous gland hyperplasia and Spitz nevus, and the coincidence rate of clinical diagnosis was only 20%. The most common dermoscopic features of trichoderma included yellow-white homogeneous area (90%), purplish red homogeneous area (80%), irregular branched vessels (60%), and white streaks (60%).  Conclusion: The misdiagnosis rate of trichommatoma is high. The most common dermoscopic features of trichoderma are yellow-white homogeneous area, purplish red homogeneous area, irregular branched vessels, and white streaks.
