Is a Shave Biopsy Enough to Detect Melanoma?
Two years ago I had a shave biopsy on my lower leg. The lesion was blue/black in color, slightly raised, and 3mm. Those were the only abnormalities. The dermatologist performed a shave biopsy but apologized with having to go deeper to get to the lesion. The biopsy report showed a complete benign solar lengtigo. After the biopsy, some of the blue/black lesion was still there. In the two years, the remaining part of the lesion has not changed in color, size, shape, texture, or elevation. I have read that a shave biopsy is not enough to detect melanoma. Can I trust my results and move on?
If you are concerned, I think that it is best to have a lesion reevaluated. A shave biopsy, if it is large enough (gives a good representation of the specimen), can be enough to diagnose melanoma.
