Brief Answer:
Linear melanonychia - most likely a benign melanocyte proliferation

Detailed Answer:
Hello. Thank you.

I am Dr. kakkar(Dermatologist). I have noted your concern and I have viewed the image.

A faintly dark, thin, uniformly coloured line and with well defined edges along the nail plate is most likely to be due to a benign melanocytic proliferation rather than due to a subungual melanoma. A subungual melanoma usually presents with a broader, variably coloured line (blue, black, red etc) along the nail plate which is illdefined, irregular bordered and usually also extends on to the adjacent nail fold (Hutchinson's sign).

Brief Answer:
No follow up needed.

Detailed Answer:
Hi.

Its benign. No follow up needed.
You may just keep a watch on it- if it changes over time i.e gets broader, ill defined, irregular, develops color variegation or involves the proximal nail fold.
