INTRODUCTION
Dermatofibromas (DF) are common benign skin lesions that can be easily diagnosed clinically in most cases. However, it can be clinically difficult to distinguish DFs from other lesions such as dysplastic nevi or malignant melanoma (1).
It is mildly predominant in female patients, but often affects young or middle-aged adults. It reveales as flat, firm, single or multiple papules, plaques or nodules, clinically characterized by a variety of colors from light brown to dark brown, purple, red or yellow (2). It is a soft tissue and bone neoplasm composed of fibroblastic and histiocytic components without nuclear pleomorphism or histological anaplasia (3,4). Dermoscopy (dermatoscopy or epiluminescence microscope) is an in vivo, non-invasive technique that reveals a new dimension of clinical-morphological features in pigmented and non-pigmented skin lesions (2). In previous studies, the presence of pigment network and central white patch has been defined as the typical dermoscopic appearance of DF (3). However, Zaballos et al. identified a total of 11 dermoscopic patterns of DFs, one of which is subtype, including different dermoscopic findings as well as these typical clinical dermoscopic findings (2). The purpose of this prospectively designed study is to re-evaluate the dermoscopic findings and patterns of DFs with a different perspective.
