User avatar Hello,Firstly I could not have a look at the photo you sent since it did not get uploaded.However,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.

User avatar Hello.I did see the image this time.It would be prudent to make sure that it is nothing more than an injury based nail change.Has it grown bigger or remaining the same?
