ABSTRACT
A 59-year-old farmer was admitted to the Department of Trauma Surgery because of pain associated with the presence of a tumour on the side of the right thigh. The patient stated that his biggest problem was great difficulty in moving and handling agricultural machinery due to the aforementioned lesion. On physical examination, the patient presented with numerous cutaneous and subcutaneous neurofibromas, as well as one large plexiform neurofibroma. Diagnosis of Neurofibromatosis type 1 was established, based on National Institutes of Health diagnostic criteria. Moreover, molecular genetic testing found known pathogenic mutation p.Arg1769* in one of the alleles of NF1 gene (heterozygote), typical for Recklinghausen disease. The big plexiform neurofibroma in the patient was not operated on because of lung cancer.
