[Solitary neurofibroma of the maxillary sinus].
Neurofibromas are benign tumours of peripheral nerve tissue, frequently associated with neurofibromatosis type I. Their isolated occurrence in the maxillary sinus is rare, with only 6 cases described in the literature. We present the case of a 70-year-old woman who consulted for left hemifacial paresthesias of 10 years' evolution. CT showed a heterogeneous lesion in the left maxillary sinus, eroding its lateral wall without signs of infiltration. Endoscopic surgery with nasalisation of the maxillary sinus was performed. The pathology was neurofibroma (positive for S-100 protein and vimentin). After 18 months, no tumour growth has been found.
