Almost all women, presumably up to 90%, and particularly those with dark hair and complexions, note some degree of hyperpigmentation during pregnancy. Patients are often deeply concerned by this condition, and may view these changes with uneasiness, yet hardly ever do they voluntarily express their concerns [21].

There is usually a mild generalized pigmentation, most marked in areas that are already slightly darker than surrounding skin, such as the nipples, areola, neck, upper back, periumbilical skin, and midline of the abdomen (Figs. 2.1–2.3). Other areas that may perceptibly darken are areas of friction such as the medial thighs, the perineum, and the axillae. In addition, freckles, nevi, and recent scars may darken and even enlarge during gestation [1]. Generalized hypermelanosis may rarely develop, and its occurrence suggests hyperthyroidism [11].
