title: [Eruptive melanocytic nevi after chemotherapy].
abstract: BACKGROUND
  Induction of melanocytic naevi by chemotherapy in children is reported in the literature. The reason for this phenomenon is not known yet.
  
  
  METHODS
  We present a 6-year-old girl who fell ill with acute lymphoblastic leukemia at the age of 2 years. After a combined chemotherapeutic treatment for 2 years followed by complete remission of leukemia, many (> 100) small pigmented naevi appeared over the whole body. The naevi did not show features suggestive of dysplasia.
  
  
  CONCLUSIONS
  Patients with excess numbers of melanocytic naevi constitute a risk group for malignant melanoma, therefore periodic skin examination is recommended.
