Neonatal Erosions and Ulcerations in Giant Congenital Melanocytic Nevi

: We report 10 cases of neonatal erosions or ulcerations in giant congenital melanocytic nevi. Histopathologic examination, performed in eight cases, demonstrated benign findings. Clinical follow‐up for an average of 3.8 years (range 2 weeks to 8 years) has not revealed the development of cutaneous melanoma. We conclude that erosions or ulcerations in giant melanocytic nevi in neonates are often benign and do not necessarily signify the presence of cutaneous melanoma.
