Melanoma T2 The Color Atlas of Family Medicine, 2e YR 2013 FD 2013 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-176964-8 LK accessmedicine.mhmedical.com/content.aspx?aid=57681621 RD 2024/03/29 AB A 40-year-old woman noticed a new dark spot on her neck (Figure 172-1). On examination the spot was 8 mm in its longest diameter, was asymmetrical with irregular borders, and had variation in color. A scoop shave biopsy demonstrated melanoma in situ. The spot was excised with 0.5 cm margins and no residual tumor was found in the excised ellipse. She has a near 100% chance of complete cure.
