[Neonatal curettage of giant congenital nevi].
OBJECTIVE
All agree upon the need for early treatment of giant congenital nevi, basically because of the risk of melanoma degeneration, estimated at about 5 p. 100. Another reason is the cosmetic, psychological and social impact of such nevi. The aim of this study was to assess neonatal curettage of giant congenital nevi as an alternative to classical surgery.


METHODS
Between 1996 and 1999, the curettage technique was used in 14 newborns with giant congenital nevi. Three nevi were located on the scalp, 4 on lower limbs and 7 on the trunk with a jacket configuration in 1 case and a cape configuration in 4.


RESULTS
Curettage achieved 70-95 p. 100 clearing of the giant nevi in 10 of the 14 children. Four of the children developed hypertrophic scar tissue which resolved with time. Secondary hair growth was observed in 5 cases. Outcome was better when the curettage was performed very early (before 2 weeks of life).


CONCLUSIONS
Curettage is a surface technique proposed when surgical excision cannot be performed because the surface is too large or the localization is incompatible with surgery. Curettage is a simple low-cost technique which provides particularly satisfactory cosmetic results for very extensive giant congenital nevi. The risk of malignant transformation is greatly reduced although not totally. Regular clinical surveillance under conditions greatly improved by the clearing should help reduce the risk.
