Brachial plexus schwannomas are rare tumors. They are benign nerve sheath tumors and only about 5% of Schwannoma arise from the brachial plexus. They pose a great challenge to surgeons due to their rare occurrence and complex anatomical location. We present two cases who presented with a supraclavicular swelling, that were proven to be schwannoma on histopathology.

Schwannomas are slow-growing mesenchymal neoplasms that arise from Schwann cells with low malignant potential. These uncommon neoplasms are nerve sheath tumors that arise at almost any anatomical site. The majority of schwannomas are benign, and few are malignant. The current study presents the rare case of an anal schwannoma that was successfully treated by surgery; there are few such cases pr...

Ganglioneuroma is a benign tumor, affecting the central nervous system, commonly seen in children and young adults. Non-cranial ganglioneuromas are seen predominantly in the posterior mediastinum and retroperitoneum. Paratesticular neoplasms are extremely rare and are susceptible to clinical misinterpretation as malignancy. Tumors of nerve origin are a rarity in the paratesticul...

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...

Laryngeal schwannomas are rare, benign tumors, most often arising from the superior laryngeal nerve. We describe a case of a 68-year-old female with a laryngeal schwannoma of the recurrent laryngeal nerve after traumatic injury. We postulate that trauma to the recurrent laryngeal nerve during thyroidectomy or thyroplasty incited growth of a nerve sheath tumor. This is the first reported case of...

OBJECTIVE To assess prevalence of plexiform neurofibroma in children and adolescents with type I neurofibromatosis and its malignant potential. METHODS A retrospective study was conducted through analysis of the database at Centro Nacional de Neurofibromatose [Brazilian Neurofibromatosis Center], collected from the following reference services between 1996 and 2004: Instituto de Dermatologia ...

PURPOSE To investigate whether elevated glucose metabolism in neurofibroma, determined by [F18]-FDG-PET, is correlated with cell density in MRI, as expressed through the apparent diffusion coefficient. MATERIALS AND METHODS Patients diagnosed with neurofibromatosis type 1 and peripheral nerve sheath tumors (PNST) were enrolled in this prospective, IRB-approved study. After a single [F18]-FDG ...

Schwannomas also known as Neurilemmoma, are benign encapsulated slow growing tumors, which arise from Schwann cells of the peripheral nerve sheath. They usually occur in head and neck region, but rarely oral cavity. We report a case Schwannoma tongue 49-year-old male patient, who presented with growing, painless lesion involving left side dorsum tongue. Patient underwent Magnetic Resonance Imag...
