Carbon Dioxide Cryotherapy for Treatment of Nasal and Perinasal Congenital Melanocytic Nevi.

Congenital melanocytic nevi, reported in 1% to 6% of newborns. There are many complications the most dangerous is the malignant transformation, but the most depressive is the cosmetic one specially for facial lesions. There is a wide range of treatment modalities none of them provide an acceptable solution for facial lesions. In this study we provide a simple, cheap and effective treatment modality for nasal and perinasal congenital melanocytic nevi. In our study, significant improvement was observed with no repigmentation throughout the follow-up period. We conclude that carbon dioxide cryotherapy is an effective treatment modality for nasal and perinasal congenital melanocytic nevi that should be used by others to stand on its long-term persistence and possible complications.
