OBJECTIVES to analyze the survival in juvenile melanoma. METHODS retrospective study conducted by hospital record review and cancer records of patients aged 0 to 19 years, with histologically proven melanoma and treated between 1997 and 2017 at the Erasto Gaertner Hospital in Curitiba-PR. RESULTS the sample comprised 24 patients, female (62.5%), mean 14.14 ± 4.72 years old, with head and neck melanoma (37.5%), chest (25%) and extremities. (20.8%). Signs and symptoms at diagnosis were increased lesion size (25%), bleeding (20.8%) and pruritus (16.6%). There was a Breslow II and IV index and Clark IV level, with a statistical tendency between Breslow IV and death (p = 0.127), and significance between Clark V and death (p = 0.067). Nine (37.5%) patients had metastases, six (25%) with distant metastases died (p = 0.001), five were girls (20.8%). Surgery was the standard treatment and chemotherapy the most used adjuvant (37.5%). The average time between diagnosis and death was 1.3 ± 1.2 years and survival were 3.7 ± 3.2 years. CONCLUSION there was a delay in diagnosis, high morbidity and mortality and average survival less than five years.
