[Survival analysis in patients with cutaneous malignant melanoma].

Introduction: Cutaneous malignant melanoma (MM) takes only 3% of all malignant tumours of the skin, but for reason of its increased frequency and pronounced tendency to rapid growth and metastases, it causes 60% of total lethal outcomes due to malignant tumours of the skin [1]. Primary MM is a diagnostic problem because of the great variety of its clinical features. Asymmetric configuration, irregular border, speckled color(r)diameter of more than 6 mm, and elevation of the surface, suggest suspicion of malignant alteration, but even then misdiagnosis is possible.
