Malignant peripheral nerve sheath tumors (MPNST) are rarely encountered in the paranasal sinuses and frontal skull base. We present histopathological findings, cytometric DNA measurements, and the preliminary results of comparative genomic hybridization analysis of a 46-year-old male patient with a frontobasal MPNST. The tumor was resected via the endonasal approach. No tumor recurrence was det...

5 à 10% des patients atteints de neurofibromatose de type 1 (NF1) développent des tumeurs malignes des gaines des nerfs périphériques (Malignant peripheral nerve sheath tumor: MPNST) contre 0.001% dans la population générale. A travers deux observations et une revue de la littérature nous discuterons la spécificité de la transformation sarcomateuse au cours de la neurofibromatose de type 1. Pan...

Hybrid peripheral nerve sheath tumors (HPNST) are relatively recently described tumors. With ongoing research, a considerable amount of important findings have been made, much of which has substantial clinical implications. However, a comprehensive review of the whole topic has not been published in the literature so far. In the presented manuscript, the various hybrid tumors are discussed sepa...

Although somatostatin receptors have been detected in many normal and neoplastic tissues, little is known of their expression and function in peripheral nerve tumors. In the present study, we examined the expression of all 5 somatostatin receptor subtypes (sst1-5) in 3 normal peripheral nerves, 3 traumatic neuromas, 27 schwannomas, 18 neurofibromas, and 177 malignant peripheral nerve sheath tum...

We report a patient with multiple endocrine neoplasia type 1 (MEN-1) and an aggressive malignant peripheral nerve sheath tumor (MPNST) arising from a ganglioneuroma of the adrenal gland. Patients with MEN-1 require careful consideration of other tumor associations, including MPNST, as it can portend a poor prognosis. MEN-1 and MPNST have not been reported. We report a patient with multiple endo...

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...

SUMMARY We report the CT and MR imaging findings in a patient with malignant peripheral nerve sheath tumor in the right nasolabial area, which exhibited typical imaging features of cystic adenoid carcinoma.
