Schwannomas (neurilemmomas) are benign tumours of Schwann cells. They can arise from peripheral, cranial, or autonomic nerves. Malignant transformation of benign schwannoma is very rare. Schwannoma is treated by complete surgical excision. In this case report, we present the demographics and clinico-pathological profile of a case of Schwannoma in the tongue. A 40-year-old male patient presented with a slow-growing swelling beneath the tongue for the past 5 weeks. On intraoral examination, a 2.5×1.5 cm mass was seen at the ventral aspect of tongue. There was no enlargement of lymph nodes. Excisional biopsy was done under local anaesthesia. Histopathological features were suggestive of schwannoma. Despite its rarity of occurrence intra-orally, a differential diagnosis of Schwanomma should be considered for proper management as it favours good prognosis. Key Words : Schwannoma, Neurilemmoma, Schwann cells, Neurofibroma.

Cystic Schwannoma

Schwannomas are benign tumours that arise from the Schwann cells of nerve fibres. They commonly occur in the head and neck, mediastinum and extremities. They are extremely rare in the pelvis. These are usually slow growing tumours and are often detected incidentally. Pre-operative diagnosis is extremely difficult as there are no definitive signs on imaging. Aspiration biopsy is often inconclusive or misleading. Surgical excision is both diagnostic and therapeutic. As these tumours are often large in size, open excision is most commonly performed. We describe a case of a large, cystic schwannoma of the pelvis causing bladder outlet obstruction and bilateral hydroureteronephrosis. Complete surgical excision was performed laparoscopically.

AbstractA huge schwannoma, located in the retroperitoneal space, is found very rarely. The main purpose of this paper is to present the case of a giant retroperitoneal schwannoma which partly invaded L4 vertebral body. The secondary purpose is to summarize the case-report articles on retroperitoneal schwannomas. A circumscribed heterogenic tumour was revealed on transabdominal sonography. It extended into the right retroperitoneal space. CT and MRI revealed a paravertebral tumour in the size of 11 cm × 9 cm, which is causing a partial lysis of L4 vertebral body (15% of vertebral capacity), expanding intravertebral foramen and filling the right retroperitoneal space. A preoperative core needle biopsy was performed and a benign schwannoma was diagnosed. A complete surgical excision of the tumour was achieved by a two-step operation. During the first step, the neurosurgeons made L4 hemilaminectomy, facetectomy and a transverse process resection by posterior extended approach. The general surgeons excised the residual retroperitoneal part of the tumour by midline transabdominal approach 10 days later. The diagnosis of benign schwannoma was verified histochemically. There were no sign of tumour recurrence or spine destabilization at the six-month follow-up. In conclusion, although majority of giant retroperitoneal schwannomas can be completely removed performing one-step operation, a preoperative consideration about rationality of two-step operation should be mandatory when tumour destructs a part of vertebral body. Our case shows that the combined two stage complete surgical excision of a giant retroperitoneal schwannoma, eroding 15% of L4 vertebra’s osseous capacity, is effective and does not have any negative influence on spinal stability.

Background. Osteoblastoma is a rare benign tumor. This tumor is characterized by osteoid and bone formation with the presence of numerous osteoblasts. The lesion is more frequently seen in long bones and rarely involves maxilla and mandible. Due to its clinical and histological similarity with other bone tumors such as osteoid osteoma and fibro-osseous lesions, osteoblastoma presents a diagnostic dilemma.Case Report. Very few cases of osteoblastomas involving maxillofacial region have been reported in the literature. This case report involves osteoblastoma involving right maxilla in an 18-year-old male patient. Following detailed clinical examination, radiological interpretation, and histopathological diagnosis, surgical excision was performed. The patient was followed up for a period of 3 years and was disease free.Summary and Conclusion. Benign osteoblastoma involving jaw bones is a rare tumor. There is a close resemblance of this tumor with other lesions such as fibro-osseous lesions and odontogenic tumors and thus faces a diagnostic challenge. Surgical excision with a long-term follow-up gives good prognosis to this lesion—Benign Osteoblastoma.

CONTEXT: Neuroglial ectopia has been defined as a mass composed of differentiated neuroectodermal tissue isolated from the spinal canal or cranial cavity and remains rare. This lesion has to be considered in the differential diagnosis among newborn infants with classical symptoms of respiratory distress, neck mass and feeding difficulties. We present a rare case of extensive parapharyngeal and skull base neuroglial ectopia in 6-month-old girl who presented respiratory and feeding obstruction at birth. CASE REPORT: A six-month-old girl who presented upper respiratory and feeding obstruction at birth and was using tracheostomy and gastrostomy tubes was referred to our institution. Complete surgical excision of the mass consisted of a transcervical-transparotid approach with extension to the infratemporal fossa by means of a lateral transzygomatic incision, allowing preservation of all vital neurovascular structures. The anatomopathological examination showed a solid mass with nests of neural tissue, with some neurons embedded in poorly encapsulated fibrovascular stroma, without mitotic areas, and with presence of functioning choroid plexus in the immunohistochemistry assay. Neurovascular function was preserved, thus allowing postoperative decannulation and oral feeding. Despite the large size of the mass, the child has completed one year and six months of follow-up without complications or recurrence. Neuroglial ectopia needs to be considered in diagnosing airway obstruction among newborns. Surgical treatment is the best choice and should be performed on clinically stable patients. An algorithm to guide the differential diagnosis and improve the treatment was proposed.

Angioleiomyoma is a benign smooth muscle and vessel tumor; laryngeal localization is extremely rare with only 24 cases described in the literature; moreover, it should be considered in the differential diagnosis of laryngeal mass. Endoscopic complete surgical excision with dissection along capsule is now considered the gold-standard treatment for small and well-circumscribed laryngeal angioleiomyoma. We present a case of laryngeal angioleiomyoma successfully treated with carbon dioxide laser technology which resulted in a bleeding reduction and adequate hemostasis with less tissue damage and good functional outcome.

Thymic neuroendocrine carcinomas (carcinoid) are rare tumors. They have malignant potential, the capacity for distant metastasis, and often present with associated endocrinopathies. This report describes a patient who was diagnosed with thymic carcinoid and Cushing syndrome at age 19 that, despite complete surgical excision of his tumor, developed local recurrence with distant metastases to his brain, lungs, and bone. We discuss the evolution of this patient's illness as well as the therapies used in his care. Due to the nature of these tumors to recur both locally and distant, the importance of aggressive surgical management is emphasized. We also discuss the role of adjuvant therapy, which in our case consisted of chemotherapy, radiotherapy, and several new therapies including an antiangiogenesis agent and a tyrosine kinase inhibitor.

Primary Retroperitoneal

Paragangliomas are extra-adrenal tumors of the autonomic nervous system and may be found within the skull base, neck, chest, and abdomen. When presenting within the abdominal cavity, they may arise as a primary retroperitoneal neoplasm and can mimic vascular malformations or other conditions related to specific retroperitoneal organs such as the pancreas, kidneys, or adrenals. Retroperitoneal paragangliomas are mostly benign with good prognosis; however, they can present with abdominal pain, palpable mass, or hypertensive episodes. Patients should be initially evaluated with catecholamine levels, followed by computed tomography or magnetic resonance imaging to locate the primary lesion. Surgical excision remains the mainstay of treatment, although advanced disease and proximity to vital organs can make excision difficult or impossible. This case report describes a patient who initially underwent work up for a suspected pancreatic head mass which was discovered to be a retroperitoneal paraganglioma by frozen section.

Congenital Granular Cell Epulis

Abstract Background A congenital granular cell epulis (CGCE) is a rare benign lesion of uncertain histologic origin that is found on the mucosa of the alveolar ridges of newborn babies. There have been less than 250 reported cases of CGCE. They are most commonly found in the anterior maxilla region in female infants. Case Report An 8-week-old female was referred from the Neonatal team with a 10mmX5mm lesion found at birth on the mucosa of the anterior maxilla. She was seen in the Oral and Maxillofacial Department where her parents reported that the lesion was causing discomfort when feeding and they were keen for its removal. On initial medical examination the patient was diagnosed with a Grade 1 ejection systolic murmur and was awaiting further cardiac investigations. With this in mind and the young age of the patient, it was decided an excisional biopsy of the lesion under local anaesthesia (LA) would be the safest option. The lesion was excised uneventfully when the patient was 9 weeks old. It was shown to be a congenital granular cell epulis following histopathological analysis. The patient was reviewed 8 weeks post-operatively. There were no signs of recurrence, the infant’s feeding had improved drastically, and she was thriving. Discussion CGCE is a rare and interesting lesion in neonates. Early diagnosis and treatment of CGCE is essential in facilitating infant feeding. This report highlights that a well-planned surgical excision under LA is a well-tolerated and safer option which is welcomed by parents.
