Melanocytic lesions and dermoscopy in childhood : diagnosis , therapy and foloving
Knowledge of pigmented lesions dates back to ancient times beginning with Hippocrates and Celsius, who called such outgrowths naevi nigricans. In the 16th century they were described by Russius Lauretius and then in 17th century by Highmore as tumors resembling coal. During the 20th century those tumors had different names: melanotic tumor, melanotic cancer, anthracite cancer etc. One of recent publications is the thesis by Bonnta in Lion (1911) titled ”Melanosis and melanotic tumors“. In 1967 an international body within the World Health Organization was established for the evaluation of diagnostic methods and treatment of melanoma, and under its auspices comparative clinical research has been conducted worldwide [1].
