OBJECTIVE To evaluate the contribution of ultrasonography in the diagnosis of neurilemmoma and to establish if a round or round-like shape adds useful information for ultrasonographic diagnosis. METHODS Archives of ultrasound findings in 203 patients (127 males and 76 females, aged 14 -72 years old, mean 32.1 +/- 25.8) with limb mass were reviewed. The maximal and minimal diameter of the lesi...

•A large cervical neurilemmoma-like leiomyoma can simulate a retroperitoneal tumor.•They are extremely rare tumors that require adequate bleeding control.•Comprehensive anatomo-pathological study should be done to rule out malignancy.

Schwannoma, also called neurilemmoma, is a benign neoplasm of peripheral nerve sheath. An infrequent location of a multiple intraoral plexiform schwannoma arising on the branches of the facial nerve in the vestibular mucosa of a young male patient is here discussed. Surgical treatment has been discussed on the base of histological findings and diagnosis.

the neurilemmoma is a benign neoplasm of schwann cell origin. one of the histopathologic subtypes of this tumor is ancient schwannoma which is characterized by degenerative alterations including cystic change, calcification, hemorrhage, and hyalinization. intraosseous schwannomas especially ancient ones are rare tumors. here we present a case of intraosseous ancient schwannoma in the lower jaw ...

Primary solitary tumours of the peripheral nerve trunks are relatively infrequent. Three such tumours have been treated at Hammersmith Hospital during the last four years, but a search of the hospital records for the period 1939-1950 has not shown any similar cases. (Solitary tumours of the auditory nerve and spinal nerve roots are not included in this report.) In these three patients the tumou...

Neurilemmomas are well-encapsulated, benign, slow-growing tumors originating from Schwann cells of the nerve sheath surrounding cranial, peripheral, or autonomic nerves. Intraoral neurilemmomas are relatively rare and have a wide variety of morphologic and radiologic features. This makes differential diagnosis difficult, and only histopathological features can lead to a definitive neurilemmoma ...
