Schwannomas are peripheral nerve tumours of nerve sheath origin. We report one case of cervical schwannoma originating from the brachial plexus. A 56-year-old man presented with a slow-growing mass on the right side of his neck that had been noted for more than 10 years. During operation, a wellencapsulated mass was seen beneath the brachial plexus with adhesion to the plexus element. It was reported as a schwannoma. Three days after surgery, the patient had a motor deficit of the right upper arm and neurological examination showed a CV nerve deficit. The neurological function recovered completely after three months. In addition, the other five cases of cervical schwannoma seen in our hospital between March 1990 and June 1998 are also reviewed. All patients had surgery. The pre-operative symptoms, impressions, and post-operative neurological status were shown and discussed. Only two cases were diagnosed as neurogenic tumour pre-operatively. Post-operatively, one patient had transient neurological deficit and another one had permanent deficit.

Obstetric brachial plexus palsy is not uncommon. However, lesions masquerading as obstetric brachial plexus palsy are rare. A child with a cervicothoracic arachnoid cyst masquerading as obstetric brachial plexus palsy is presented, and the relevant literature is reviewed. A girl born by vaginal delivery at full term without any antecedent risk factors for obstetric brachial plexus palsy was noted to have decreased movements of the right upper extremity. After 7 months, there was no improvement. An MRI scan was obtained, which revealed a cervicothoracic spinal extradural arachnoid cyst. During surgery, the cyst was found to communicate with the dura at the axilla of the C-7 nerve root. The cyst was excised in toto. Six months later, there was improvement in the infant's neurological status. This case illustrates that spinal arachnoid cysts should be entertained in the differential diagnosis when a child presents with obstetric brachial plexus palsy without known antecedent risk factors for obstetric palsy.

Extensor Carpi Radialis

ABSTRACTRadial nerve is usually a branch of the posterior cord of the brachial plexus. It innervates triceps, anconeous, brachialis, brachioradialis, extensor carpi radialis longus muscles and gives the posterior cutaneous nerve of the arm, lower lateral cutaneous nerve of arm, posterior cutaneous nerve of forearm; without exhibiting any communication with the medial cutaneous nerve of forearm or any other nerve. We report communication between the radial nerve and medial cutaneous nerve of forearm on the left side in a 58-year-old male cadaver. The right sided structures were found to be normal. Neurosurgeons should keep such variations in mind while performing the surgeries of axilla and upper arm.

Schwannomas are benign tumours arising from Schwann cells in the peripheral nerve. The schwannoma of the accessory nerve is a very rare entity. We report a case of Schwannoma of the extracranial accessory nerve. A 22-year-old man presented with a slow-growing mass, located on the right upper neck. The patient did not have any neurological deficit. CT scan showed a hypodense mass behind sternocleidomastoid muscle. The suspected diagnosis was an adenopathy of the accessory spinal chain. Surgery was done via transcervical approach. The histopathological analysis concluded with a diagnosis of schwannoma. No recurrence was noted at the follow-up examination 29 months after surgery.

Objective: To present a case of cervical vagal schwannoma and describe our experience with the clinical presentation, surgical management and outcome of an elderly patient with this pathology. Methods: Design: Case Report Setting: Tertiary Public Hospital Patients: One Result: A 65-year-old lady presented with a recently enlarging, pulsatile right sided neck mass that had been asymptomatic for 15 years. Contrast CT revealed a circumscribed non-enhancing heterogenous 4 x 4 x 7 cm mass splaying the right internal jugular vein and common carotid artery. A neurogenic tumour was considered, and the mass was excised from the vagus nerve with preservation of adjacent structures. Final histopathologic reading was schwannoma. However, the patient succumbed to complications following a second surgery for expanding hematoma. Conclusion: Schwannomas are benign, slow growing tumours that arise from Schwann cells of the nerve sheath. Cervical schwannomas originating from the vagus nerve are rare, but should be considered in patients presenting with solitary neck masses. Surgical extirpation is still the treatment of choice for nerve sheath tumours and recurrence is uncommon.  Efforts should be made to preserve unaffected structures and patients should be counseled preoperatively on the possible high risk of morbidity especially in the elderly group where close follow up and aggressive rehabilitation should be instituted following surgery.   Keywords: Cervical schwannoma, vagus nerve, neurogenic tumour; parapharyngeal space

Introduction A liposarcoma is a rare cancer of connective tissues that resemble fat cells under light microscopy. Case History A 73-year old female patient presented to our tertiary cancer centre with an eight-year history of a large, slow-growing painless mass in the right axilla. Magnetic resonance imaging showed a lipomatous, well-circumscribed mass of dimension 30 × 16 × 10cm extending towards the right clavicle and causing deformation to the right chest wall and right breast. Surgery revealed a large tumour that had stretched all three cords of the brachial plexus. Histopathology was consistent with a diagnosis of a low-grade liposarcoma. After a period of neuropraxia, the patient returned to normal activities 4 months after surgery. Conclusions Although extremely rare, low-grade liposarcomas of the brachial plexus should be considered in the differential diagnosis of a slow-growing axillary mass. Referral to a tertiary sarcoma centre is essential for an appropriate diagnosis, adequate treatment, and long-term follow-up.

ABSTRACTAngioleiomyoma is a benign tumor of vascular smooth muscle origin. Although many factors have been implicated in its pathogenesis, presence of lipometaplasia suggests its hamartomatous nature. This tumor presents as a painful nodular mass in extremities. Thus angioleiomyoma should be considered as a differential diagnosis of any solitary painful mass of forearm. Herein we report a case of 37-years-old female presenting with a slow growing mass in the right forearm. Histopathological and immunohistochemical examination confirmed the diagnosis of angioleiomyoma.

Abstract- Pleomorphic hyalinizing angiectatic tumor (PHAT) is a rare, slow-growing mass, which is locally aggressive and classified as tumors of borderline malignancy. In this study, we report a case of subcutaneous ankle mass in 43-year-old female since 2 years ago with a pathological diagnosis of PHAT, characterized by clusters of ectatic, fibrin-lined, and thin-walled vessels which are surrounded by a spindled or pleomorphic neoplastic stroma.

Ameloblastic fibroma is an uncommon mixed neoplasm of odontogenic origin with a relative frequency between 1.5 – 4.5%. It can occur either in the mandible or maxilla, but predominantly seen in the posterior region of the mandible. It occurs in the first two decades of life. Most of the times it is associated with tooth enclosure, causing a delay in eruption or altering the dental eruption sequence. The common clinical manifestation is a slow growing painless swelling and is detected during routine radiographic examination. There is controversy in the mode of treatment, whether conservative or aggressive. Here we reported a 38 year old male patient referred for evaluation of painless swelling on the right posterior region of the mandible associated with clinically missing 3rd molar. The lesion was completely enucleated under general anesthesia along with the extraction of impacted molar.

Brachial plexus is the plexus of nerves, that supplies the upper limb.Variations in the branches of brachial plexus are common but variations in the roots and trunks are very rare. Here, we report one of the such rare variations in the formations of the lower trunk of the brachial plexus in the right upper limb of a male cadaver. In the present case the lower trunk was formed by the union of ventral rami of C7,C8 and T1 nerve roots. The middle trunk was absent. Upper trunk formation was normal.
