Discoloration Of The Toe Due To Repeated Injury. Cure? History Of Asthma.
Thanks for posting your query.
Very light brown colored lines on the toe are usually a result of repeated trauma. This chronic repeated trauma injures the growth plate and difference in the growth of toe nail in the different areas sometimes manifests as light colored lines.
In such cases usually no treatment is needed and this growth discrepancy resolves on its own once the exposure to trauma is over.
Melanomas are commonly associated with darker pigmented areas with ulcerations, irregular margins, recent change in shape and size, sometimes pain and bleeding. From your description it is least likely to be a melanoma.
A direct examination by a dermatologist will help in confirmation of the diagnosis.
