Retrospective analysis of melanocytic lesions in children at the National Cancer Institute-RJ.

Skin cancer is the most common neoplasm in Brazil. Melanoma accounts for 4% of these neoplasms. Although childhood melanoma is rare, there is evidence that its incidence is increasing, placing it among the most important public health problems for the future. This work sought to conduct a retrospective review of cases of suspected melanocytic skin lesions in children, their diagnosis and management, and evaluate the sentinel lymph node biopsy method in some cases of cutaneous melanoma.
