是由皮膚科醫生Dr. Dana Stern所發表的觀點論述
Patient is an 80-year-old Latina female who presents with a complaint of
a dark pigmented band at the left first fingernail that has gotten wider within
the last several months. She is referred by another dermatologist.
There is no family history of skin cancer or melanoma. She denies trauma to the digit.
I recommended that the nail be biopsied given the recent change in width,
the involvement of the thumb (the most common digit for melanoma),
the single digit involvement, as well as the appearance of the nail
(the band has several colors within it and is very dark).
Multiple pigmented bands are very common in certain ethnic groups,
however, when I see a single band I am more concerned.
The biopsy that I performed showed a melanoma in situ,
which is an early and treatable stage of melanoma.
