Dark skin in axilla: Acanthosis nigricans is a skin disorder in which there is darker, thick, velvety skin in body folds and creases. Because acanthosis nigricans usually only changes the skin's appearance, no treatment is needed. Treat any underlying medical problem that may be causing these skin changes--obesity, diabetes, female hormones, or lymphoma. Some cases are genetic.
