Malignant Peripheral Nerve Sheath Tumor in the Maxilla: Report of a Rare Case
Malignant peripheral nerve sheath tumor (MPNST) is a rare malignant tumor that develops either from a preexisting neurofibroma or de novo. The cell of origin is believed to be the Schwann cell and possibly other nerve sheath cells. In this report, we describe a rare case of MPNST that arise from the socket of second left maxillary molar that has been already extracted in a young man. He was ref...
متن کاملMalignant peripheral nerve sheath tumor of the parotid gland.
Malignant peripheral nerve sheath tumors originating from the parotid gland are extremely rare. A 76-year-old male patient underwent an incisional biopsy for an ulcerated mass in the anteroinferior aspect of the left auricle. The diagnosis was made as malignant mesenchymal tissue sarcoma, but the patient refused treatment. Upon progressive growth of the mass within two months, he underwent a pa...
متن کاملIntrathoracic Malignant Peripheral Nerve Sheath Tumor: Histopathological and Immunohistochemical Features
Malignant peripheral nerve sheath tumor (MPNST) is a rare nerve sheath tumor derived from Schwann cells or pleuripotent cells of neural crest. Neurogenic tumors make about 10-20% of all mediastinal tumors. Incidence of MPNST is 0.001% in general population and 0.16% in patients with neurofibromatosis I (NF I). We report a case of 60 year female presenting with progressive cough and breathlessne...
متن کاملSuperficial malignant peripheral nerve sheath tumor: a rare and challenging diagnosis.
We reviewed the clinicopathologic features of 5 cases of malignant peripheral nerve sheath tumor (MPNST) manifesting in superficial locations associated with cutaneous neurofibromas (4 cases) or superficial peripheral nerve (1 case). Four cases had spindle cell morphologic features and were at least focally positive for S-100 protein, whereas the associated benign neural elements had more exten...
