The authors describe the case of a patient who developed during 31 months, five malignant tumours, three synchronous and two metachronous. The primitive origin and the long interval of time between the occurrence of each tumour, allow to set them in the group of Multiple Primitive Malignant Neoplasm. The authors, reviewing the classifications and the pathogenesis of these tumours, underline the importance of the follow-up in oncology patients and emphasize the role of nosographic setting in order to plan the most suitable therapeutic approach.
