This article reviews a spectrum of benign soft tissue tumors found in adults. Rather than presenting a complete review, the focus of this article is on benign tumors for which the diagnosis may be confidently made or strongly suggested on the basis of imaging. Diagnoses presented include nodular fasciitis, superficial and deep fibromatosis, elastofibroma, lipomatous lesions, giant cell tumor of...

Neurilemmoma of the orbit is a localized, encapsulated, benign nerve sheath tumour which grows very slowly and possibly intermittently, and has no distinctive clinical features (Reese, I963). When large enough it causes exophthalmos and sometimes blurring of vision through pressure on the optic nerve (Reese, I963; Sharma and Kulshrestha, I961). The motility of the eyeball may also be impaired. ...

Neurilemmoma also known as schwannoma is benign nerve sheath tumor rarely occurring in the oral cavity. Only 1% of all extracranial schwannomas show that intraoral occurrence with tongue is the commonest site and retromolar region is the least common site. It presents as encapsulated, slow growing, solitary, smooth-surfaced, usually asymptomatic tumor. We report a case of 70-year-old male with ...

A spinal neurofibroma with malignant change leading to `sarcomatous meningitis' is described in a woman of 73. Three similar cases have been found in the literature. This is an exceedingly rare complication of nerve sheath tumours in the spinal canal.

An Bras Dermatol. 2017;92(3):433-43. Dear Editor, We report the case of a 66-year-old male patient who presented with a 10-year history of a nodular mass in the right leg region. The patient referred a gradual enlargement of the lesion, which had a quick growth in the last two years. He had arterial hypertension and hypothyroidism but no history of neurological pathologies. Dermatological exami...

Introduction: Retroperitoneal schwannoma is a rare tumor that originates from the Schwann cells of peripheral nerve sheath. It mostly located in brain and spinal cord, but can affect other untypical places such as scrotum penis. Aim: The aim this study was to present two different cases retroperitoneal schwannoma. Case study: authors patients with benign malignant schwannomas (malignant sheath ...

Nerve sheath myxoma has been described as a rare neural tumor arising from Schwann cells. It is observed most frequently in the central area of the face, neck and upper extremities. In the past the term neurothekeoma was used as synonym for nerve sheath myxoma but according to new reports, they are separate entities which can be confirmed by immunohistochemistry as in our case. Oral involvement...

BACKGROUND AND IMPORTANCE Malignant peripheral nerve sheath tumors are the most common malignant mesenchymal tumors of soft tissues, but they are very rare when found to arise from a cranial nerve and when not in association with neurofibromatosis. These tumors are highly malignant and carry a poor prognosis with survival usually less than 6 months. CLINICAL PRESENTATION The authors report th...

Schwannomas are peripheral nerve sheath benign tumors which arise from the schwann cells. These neoplasms most frequently seen in 3 to 6 decade of life and affecting limbs followed by head neck region. Oropharyngeal vallecular involvement schwannomas is extremely rarely reported previous literature. We report a case 25 year old male with lesion vallecula was subsequently diagnosed as on histopa...
