Only 21 cases have been reported in the literature so far. Only four of the 21 cases were reported to be primarily originated from the maxillary sinus. In this article, a 44-year-old woman with a right maxillary sinus malignant schwannoma is presented. Right partial maxillectomy with lateral rhinotomy approach followed by a postoperative course of radiotherapy and chemotherapy was performed as the treatment. This mass was confirmed as a malignant schwannoma in histological examination and immunohistochemical staining. There was no tumor recurrence or distant metastases for 22 months after the treatment. She died from brain metastasis and sepsis 37 months after the operation.eninfo:eu-repo/semantics/openAccessMalignant SchwannomaMaxillary SinusArticle28423623910.5336/caserep.2020-74946427940
