Cutaneous Manifestations of Pregnancy

Cutaneous Manifestations of Pregnancy


During pregnancy, hormonal shifts may result in physiologic alterations in the skin, hair, and nails. Many of these changes are seen so frequently, that they are considered to be normal. Pregnancy can also alter the course of certain preexisting skin conditions and systemic diseases that have cutaneous involvement, for example:

  • Systemic lupus erythematosus and scleroderma may flare.

  • Acne may improve, or it may worsen.

  • Dyshidrotic eczema may appear de novo, or a flare-up of preexisting lesions may occur.

  • Condylomata acuminata may enlarge considerably and may proliferate.

It should always be kept in mind that common skin diseases unrelated to pregnancy should also be considered when evaluating a pregnant patient with a skin disorder.



Distinguishing Features

  • Darkening of the linea alba which then becomes the linea nigra (Fig. 23-1)

  • Darkening of the nipples and surrounding areolae, as well as darkening of the axillae, thighs, umbilicus, perineum, and external genitalia, may occur

  • Melasma (see also Cheeks). The “mask of pregnancy” (formerly known as chloasma) occurs in more than 50% of women during pregnancy. It is worsened by exposure to the sun

  • Darkening of preexisting freckles and nevi
