Abstract

Abstract:

Epidermoid cysts are common benign lesions of the skin. High-frequency ultrasound is a good method for evaluation of skin soft-tissue mass. Here, we reported a case of epidermoid cyst which was misdiagnosed by ultrasound imaging as a dermoid cyst. With retrospective analysis of the ultrasound imaging, we realized that edidermoid cysts may have following features, in which the lesion originated from the skin, and have expansive hair follicle-like structure at the skin junction, as well as have onion-like or mixed echogenic changes. Ultrasound imaging can improve diagnostic accuracy through these characteristics along with clinical information.
