The Value of Ultrasound for Differentiating Trichilemmal Cysts From Epidermoid Cysts

Objectives This study was aimed to evaluate the diagnostic performance of ultrasound (US) in differentiating trichilemmal cysts (TCs) from epidermoid cysts (ECs). Methods Based on clinical and ultrasound features, a prediction model was established and validated. 164 cysts in the pilot cohort and an...

Description
Summary:Objectives This study was aimed to evaluate the diagnostic performance of ultrasound (US) in differentiating trichilemmal cysts (TCs) from epidermoid cysts (ECs). Methods Based on clinical and ultrasound features, a prediction model was established and validated. 164 cysts in the pilot cohort and another 69 in the validation cohort diagnosed with TCs or ECs histopathologically were evaluated. The same radiologist performed all ultrasound examinations. Results For clinic features, TCs tended to occur in females compared with ECs (66.7 vs 28.5%; P
