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.
