Black line on the nail: is it always melanoma?
Video in Spanish · subtitles available
A brown or black stripe on the nail? It's not always melanoma. In this video I explain what longitudinal melanonychia is, why it appears, and when it should be checked.
A brown or black line on a nail is alarming, especially after searching online. In this video I explain what longitudinal melanonychia is, how it forms in the nail matrix, and why the majority of causes are benign. I also walk you through the signs that make it advisable to have it examined: a new band on a single nail that is widening, changing color, or becoming irregular; the Hutchinson sign; or a nail that is beginning to deform. The key, almost always, lies in how it evolves over time.
