Abstract
To analyze the characteristics of high-frequency ultrasonography of pilomatricoma and discuss the value of high-frequency ultrasonography in the diagnosis of pilomatricoma, ultrasonographic data of 71 cases (77 patients) with pilomatricoma diagnosed by high-frequency ultrasonography and pathology in our hospital from June 2013 to June 2017 were retrospectively analyzed. The location, size, shape, border, echo and blood supply status of the sonographic images were summarized. As a Result, among the 71 patients (77), there were 62 cases located at the head and neck, 11 at limbs and 4 at the trunk. 66 cases were single and 5 cases were multiple. All the tumors were subcutaneously located. The typical characteristics of pilomatricoma: it is more common in young people. They are hypoechoic nodules on hypodermatic parts of head and neck. The boundary is clear. The shape is regular, accompanied by calcification within the visible dot-like blood flow signal. There is inner calcification within the visible dot-like blood flow signal. It is concluded that ilomatricoma has certain sonographic features. High-frequency ultrasonography has a significant impact in the diagnosis.
Highlights
Pilomatricoma, known as calcifying epithelioma, is a benign tumor that is presented at the junction between the deep dermis and the subcutaneous fat
The main purpose of this study is to retrospectively analyze the high-frequency ultrasonographic data of 71 cases (77) of pilomatricoma in our hospital confirmed by ultrasonography and pathology, and summarize the characteristics of ultrasound images, so as to deepen people’s understanding in the ultrasound image of pilomatricoma and improve the diagnosis rate
Hair mother tumor is a benign nodular tumor located between the skin layer and the subcutaneous fat layer
Summary
Pilomatricoma, known as calcifying epithelioma, is a benign tumor that is presented at the junction between the deep dermis and the subcutaneous fat. It originates from hair follicle stromal cells and rarely has malignant transformation [1] Hair mother tumor is common in young people. Compared with CT and MRI, high-frequency ultrasound is convenient, fast and noninvasive for the diagnosis of pilomatricoma in the superficial area, with less cost and higher image resolution. It is a recommendable auxiliary diagnostic means. The main purpose of this study is to retrospectively analyze the high-frequency ultrasonographic data of 71 cases (77) of pilomatricoma in our hospital confirmed by ultrasonography and pathology, and summarize the characteristics of ultrasound images, so as to deepen people’s understanding in the ultrasound image of pilomatricoma and improve the diagnosis rate
