Abstract: Objective To explore the value of ultrasound in diagnosis and classification of pilomatricoma.Methods Ultrasonic features of 63 cases with pilomatricoma confirmed by operation and pathology were analyzed and summarized retrospectively.Results According to if there was calcification in the tumor,pilomatricoma cases were classified into two groups(calcific group and non-calcific group).In addition,there were three subgroups in the calcific group based on the size and disposition of calcification:subgroup Ⅰ,completely echogenic mass with strong posterior acoustic shadowing in the subcutaneous layer (n=17,26.98%);subgroupⅡ,hypoechoic nodules with tiny calcification diffused distributed(n=15,23.80%);subgroup Ⅲ,hypoechoic nodules with large calcification(n=8,12.70%).Twenty-three cases (36.51%)were distributed into non-calcific group.Conclusions Ultrasonography is valuable for diagnosis and differential diagnosis of pilomatricoma,and it is an essential examination method for the tumor before operation.
