Dermatofibromas are benign fibrohistiocytic tumors that involve the dermis. They have often a polymorphous clinical aspect, being frequently confused with other lesions varying from vascular tumors to melanoma. An important tool in diagnosis is represented by dermoscopy, which facilitates the recognition of dermatofibromas characteristic structures such as central white patch and peripheral pigment network. Although dermatofibromas are often solitary lesions, we report the case of a woman who presented two fibrohistiocytary masses, involving the calf and the thigh, the last one with an atypical aspect leading to the confusion with a malignant tumor. Furthermore, the lesions were different at both dermoscopic and histopathological examinations, needing a second histopathological opinion. The aim of our study is to emphasize the role of histopathology, which represents the diagnostic golden standard in suspicious cases and the possible connections between dermatoscopy and histology. Sometimes, even histopathology may be very difficult, needing repeated sections and even special stains.
