Melanoma in pregnancy

Abstract

Melanoma is one of the most common cancers diagnosed in pregnancy and has a high metastatic potential. As the incidence of melanoma increases, careful clinical evaluation of suspicious skin lesions remains the mainstay of early diagnosis. There is controversy in the literature as to whether pregnancy-associated melanoma has worse survival than other melanomas. Any changing-pigmented lesion should be biopsied, regardless of pregnancy hyperpigmentation. Increased lymphangiogenesis in pregnancy is associated with increased metastasis – timely diagnosis is therefore imperative. While the effect of oestrogen and progesterone on melanoma is under investigation, it is generally accepted that oral contraceptive use in not contraindicated after a diagnosis of melanoma in pregnancy. Subsequent pregnancy should be delayed for two to three years after a diagnosis of melanoma with a high risk of recurrence.
