Congenital Melanocytic Nevi and the Risk of Malignant Melanoma: Establishing
نویسندگان
چکیده
Congenital melanocytic nevi (CMN) are benign proliferations of cutaneous melanocytes clinically apparent at birth or within the first postnatal weeks (Walton et al., 1976). At least 2.5% of white infants are noted to have some type of pigmented lesion at birth, but only 1% have biopsy-confirmed nevocellular nevi (Walton et al., 1976). Prevalence of CMN ranges from 0.2% to 2.7% in lesions less than 1.5 cm in greatest diameter (Pratt, 1953; Walton et al., 1976; Alper et al., 1979) to 0.005% in lesions greater than 10 cm in greatest diameter (Castilla et al., 1981).

Large congenital melanocytic nevi are cutaneous lesions regarded by many as premalignant; estimates of malignancy incidence range from 0 to 42 percent. Given the often complex and extensive nature of large congenital melanocytic nevi resection and reconstruction, the risk of malignant transformation is a crucial factor that surgeons and families must weigh when deciding whether or not to excise...

Benign pigmented skin lesions are very common in children and can be generally classified into congenital or acquired nevi. Congenital nevi can be small, medium or large.
