Objectives:
A retrospective study on the Primary Cutaneous Malignant Melanoma in the Hospital do Servidor Público Estadual de São Paulo (HSPE-SP) analyzing its distribution according to age, sex, race and cutaneous site.
Methodology:
We studied 222 patients with Primary Cutaneous Malignant Melanoma as diagnosed at Hospital do Servidor Público Estadual de São Paulo, Brazil between the period from 1963 to 1997. A retrospective study was performed. Data were expressed as inance of caucasians (98.19%) over afro-americans (1.81) and of the female sex (69.36%) over the male sex (30.63%) was found. The predominant age on the occasion of the diagnosis was between 50 and 60 years for the women (25.32%) and between 60 and 69 years for the men (22.52%). The most frequent site of the cancer in men was the back region (29.41%) and in the lower members in the women (38.31%). The most frequent level of the tumor invasion (Clark) was IV (39.77%), and the average of tumor thickeness (Breslow) was < 0.75 mm (28.4%). A 5 years survival was observed in 73.3% of the patients.
Conclusions:
At our Hospital the incidence of Primary Cutaneous Malignant Melanoma has shown an increase in recent years; these results are compatible with the most recent international surveys.
