Fig 1
Dermatofibroma on patient's leg. Pigmented papule on patient’s leg with a dark central area consistent with a dermatofibroma. The lesion has typical characteristics of dermatofibroma, including central hyperpigmentation surrounded by slightly elevated, firm, and well-defined borders.

Fig 2
Dermatofibroma on patient's leg. Pigmented papule on patient’s leg with a dark central area consistent with a dermatofibroma. Also visible are other pigmented macules compared to the lesion of concern. The lesion has typical characteristics of dermatofibroma, including central hyperpigmentation surrounded by slightly elevated, firm, and well-defined borders.
