[Dermatofibroma or melanoma?].

Three patients (51-, 72- and 53-year old) revealed in dermoscopy dermatofibroma-like features on skin lesions at their back. According to the pattern, 3-4 dermatofibroma side-by-side could be suggested. Differences of the principle features - postinflammatory hyperpigmentation at the periphery surrounding central scar-like hypopigmentations - must also include the differential diagnosis of a melanoma.
