Dermatofibroma (DF) is a very common benign skin tumor composed of fibroblasts, histiocytes, capillaries and collagen with multiple clinical presentations and histological variants [1] . DF usually affects female patients at any age between 10 and 75 years old [2][3][4] . Most of the time it presents as a single, firm papular lesion with a slightly keratotic surface, sometimes brown pigmented or skin tone, and frequently present in the inferior extremities. Almost 6% of all dermatofibromas are associated with trauma [2,5] . Diagnosis is clinical and dermatoscopic patterns have been described as diagnostic tools. The most common presentation seen in 30-60% of all DF is a central scar-like patch with a peripheral reticular network [2,3,5,6] . Nevertheless, atypical patterns simulating melanomas, vascular tumors or basal cell carcinomas have been described in another variants of DF such as hemosiderotic dermatofibroma [2,3] .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
