Giant Bathing Trunk Naevus with Multiple Congenital Melanocytic Naevi

Abstract

Congenital nevi are hyperpigmented macular lesions that are derivatives of the melanoblasts. They occur in less than 1% of the neonates in any site of the body. The giant congenital nevus is greater than 20 cm in size, pigmented and often hairy. Between 4% and 6% of these lesions will develop into a malignant melanoma. Since approximately 50% of the melanomas develop by the age of two, and 80% by the age of seven, early removal is recommended. However, their large size poses a great treatment challenge. The objective of this paper is to present a unique case of giant nevi along with a review of the literature .
