ABSTRACT

Introduction: Malignant Melanoma (MM) is the most aggressive cutaneous neoplasm. Dermoscopy allows early identification of cutaneous melanomas.
Methods: Two study groups of patients with MM. Group 1: 1985-1999, Group 2 (with dermoscopy): 2000 to may 2005. In each case clinical and histological data were obtained.
Results: Fifty six malignant melanomas were diagnosed. Group 1: 39, Group 2: 17. There were no differences between both groups in age (media 41.8 yrs) and topography (head). But there were in: Clinical variety, group 1: nodular, group 2: lentigo maligno; Cases/year, group 1: 2.06, group 2: 3.85; Gender: group 1: males, group 2: females (p = 0.01 IC95% = 0.60-0.15). Clark was significantly lower in the second group 4 vs. 1 (p = 0.01 IC 95% = 0.32-2.51). In the first group there were 8 deceases caused by MM, in the second only 1. All of them had › 4 mm in Breslow scale.
Discussion: Malignant melanoma increased incidence, has been observed in the last decades. The head was the must frequent topography involved, although Mexican literature says it is the feet. In this study dermoscopy allowed early detection of MM in 41.17%; before this method was introduced early detection was only 12.5%. A tendency to improve survival was shown in group 2. Early diagnosis was more frequent in women who come up sooner.
Conclusion: Dermoscopy provides early diagnosis of malignant melanoma
