title: [Cutaneous melanoma: about 200 cases].
abstract: OBJECTIVE
  To analyze the clinical and pathological aspects of cutaneous melanoma and to determine the prognostic factors.
  
  
  METHODS
  This is a retrospective study about 200 cases of cutaneous melanoma collected in Salah Azaiz Institute over a period of 36 years (1969-2005).
  
  
  RESULTS
  The mean age was 55.4 years, with a slight female predominance. The tumour was developed on a pre-existent lesion in 31.5% of cases. The average delay of consultation was 18 months. The mean tumor size was 37 mm (10-180 mm). The ulcero exophytic appearance represented 45% of the cases. The tumor was metastatic in 19.5 % of cases. Hands and feet represented 53% of the tumour localizations. The treatment was curative in 71% of cases and palliative in 13% of cases. The lymph node dissection was performed in 59% of the patients. Histologically, nodular melanoma and Grade V of Clark represented 43.5 and 35% of the cases, respectively. The mean tumoral thickness was 14 mm. Chemotherapy, immunotherapy and radiotherapy were performed in 5.5%, 3.5% and 5.5% of cases respectively. The lymph node recurrences were noted in 43.6% of the patients treated with curative intent. The mean recurrence free survival was 76 months. Tumour size > 2 cm, the localization on the leg, Clark level invasion IV and the involvement of the tumour margin were significant prognostic factors for the recurrence free survival. The prognostic factors for the metastasis free survival were: tumour size, tumour localization, type of resection and finally the lymph node dissection. The 5-year overall survival was 28.5% and was influenced significantly by the tumour size, tumour localization, type of resection, involvement of the tumour margins, Clark grade, tumour thickness and finally the lymph node involvement.
  
  
  CONCLUSIONS
  The dismal prognosis can be improved by early diagnosis and especially the prevention based on the photo protection and surveillance of patients at high risk.
