Extravasation of blood in skin of the toes may cause a brown/black lesion that resembles a nevus or melanoma.
The patient will notice a dark brown or black spot "overnight." There may have been an episode of previous exercise/trauma. Solar/senile purpura is very closely related but typically occurs on the arms, dorsal hands, and chest. Talon noir represents a similar extravasation of blood of the heels.
As long as the diagnosis is assured, the lesion may be observed. It will spontaneously resolve within 1-2 months.
