Question: Dark line on fingernail


 Shanachie - Tue Dec 29, 2009 11:38 am

Hello,
I've had a dark line on my middle fingernail for more than a year now. I did not pay any attention to it because my wife is asian with dark skin and has this too. Apparently this is quite common among dark-skinned people. I became worried when someone told me that for people with white skin it is unusual and can be a sign of melanoma.
is this true? I have provided a link below with a photo showing the discoloration streak. Should I be worried? I have no further symptoms. I am 54 years old.
hoping for a reply........ http://www.moondragon.ie/nail_line.html

User avatar Hello,Longitudinal melanonychia are quite common in dark skinned.Melanoma in situ are rare in the population.Breath of 3mm or more,significant darkening in a short time,involvement of the dominant hand,Huchinsons sign in which the pigment enters the periunguinal skin ie is the nail folds,all need dermoscopic evaluation which is simple and non invasive.Those suspected would need a biopsy.While it may be a simple LM it would be prudent to get evaluated to be sure and get biopsied if required.Best wishes.

User avatar Hello,I guess you are fine and should not have anything to worry.But that should not prevent you from getting evaluated just to make sure.Best wishes.
