- Abstract: Objective:To explore high-frequency color Doppler ultrasound characteristics of extramammary Paget′s disease (EMPD) .Methods:From January 2015 to October 2019, 32 patients with pathologically confirmed EMPD were collected from the Affiliated Hospital of Jining Medical University, and characteristics of their high-frequency color Doppler ultrasound images were retrospectively analyzed.Results:Of the 32 lesions, 25 were located on the external genitalia (21 on the scrotum, 4 on the perineum) , 4 on the medial thigh, 1 on the lower abdominal wall, 1 in the perianal region, and 1 on the neck. Ipsilateral inguinal lymph node metastasis occurred in 3 patients, and bilateral inguinal lymph node metastasis in 1 patient. High-frequency ultrasonography showed no obvious abnormal ultrasound manifestations in 6 cases, and thickened skin lesions in 26 cases. According to the morphological and high-frequency ultrasound manifestations, 26 skin lesions were classified into 2 types: 21 diffuse-type lesions with unclear borders and irregular shapes, and 5 mass-type lesions with clear borders and irregular shapes. Solid and homogeneously hypoechoic areas were observed in 18 cases, and solid and heterogeneously hypoechoic areas in 8. According to the Adler blood flow classification, the 26 lesions were classified into 4 grades: 2 of grade 0, 5 of grade 1, 8 of grade 2, and 11 of grade 3.Conclusion:EMPD shows characteristic high-frequency color Doppler ultrasound manifestations, which can facilitate its clinical diagnosis.
