: Neurofibromatosis type 1 (NF1, von Recklinghausen disease) is inherited in autosomal dominant way genetic disorder, with an incidence at birth 1:3000. It is one of the most common congenital disorders. It is characterized by café-au-lait spots, neurofibromas, and less common MPTST and gliomas of the optic nerve. It is caused by germline mutations of the NF1 gene, which acts as tumor suppressor. Inactivation of the gene leads to increased activation of the kinase pathways, and in consequence, uncontrolled proliferation of cells. The disease predisposes to the development of both benign and malignant tumors. Malignant tumors, but not related to the nervous system occur in neurofibromatosis quite rare. The aim of the study is a literature review of NF1, with presentation of a patient with NF1 and coexisting numerous tumors: synchronous somatostatinoma and gastrointestinal stromal tumor with metachronous prostate adenocarcinoma and non-small cell lung carcinoma. And attempt to answer the question if there is a common pathway for oncogenesis of these four tumors....
