Differential Diagnosis


Patient accidentally discovered this asymptomatic macule while cutting his toenails. He was relieved to hear that this was not a melanoma, but rather a superficial fungal infection. It cleared after only a few days of ciclopirox olamine topical therapy. See: Rapid treatment of tinea nigra palmaris with ciclopirox olamine gel, 0.77%.   Rosen T, Lingappan A. Skinmed. 2006 Jul-Aug;5(4):201-3.
