Melanoma under 18 years and pregnancy: report of three cases.
Melanoma is an uncommon tumour in childhood. Only isolated cases in pregnant patients younger than 18 years old have been previously described, therefore the biological behaviour of cutaneous melanoma in this group of age remains largely unknown. We report a single-institution experience with three patients who developed cutaneous melanoma before the age of 18 years and became pregnant concomitantly or during the course of the disease. High tumour thickness was attributed to later diagnosis and could be responsible for the aggressive biological behaviour in these patients. This delay was in part due to patients considering changes in nevi to be normal during pregnancy. The effect of pregnancy on the prognosis of patients with melanoma, particularly the role of hormonal and immunological factors on clinical outcome, survival and risk of developing metastases, as well as the differences between adolescent and adult populations are still controversial. Since there are no specific treatment strategies for this group of patients, treatment recommendations should be established according to adult experience.
