Tissue Origin

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 well-defined mass on left retromolar region which was painless and slow growing. Diagnosis is made by histological examination and immunohistochemistry analysis to confirm the neural tissue origin of the lesion. The treatment is complete surgical excision of the lesion without recurrence.

<p class="abstract">Schwannomas are rare, solitary, slow growing, smooth surfaced and well encapsulated tumors. Schwannomas of head and neck region account for 25-40% of all the cases. Approximately 1%–12% of schwannomas occur intraorally, the tongue being the most common site. Complete surgical excision is the treatment of choice.  In this article, we describe a case of tongue schwannoma in a child, along with diagnostic and treatment options of tongue lesions. The tongue mass was completely excised via trans-oral approach using coblation method. The patient followed up for 1 year; he had an uneventful recovery and no recurrence.</p>

Rare Case Report

AbstractMalignant peripheral nerve sheath tumors (MPNSTs) are rare neoplasms, usually arising from components of nerve sheath such as perineural fibroblasts or Schwann cells. Primary scalp MPNST is an exceptionally rare entity and only few cases have been reported till date. We encountered an unusual case of giant scalp MPNST in a 70-year-old man without any history suggestive of neurofibromatosis associated with intracranial extension with underlying bone destruction. The tumor was treated with complete surgical excision followed by adjuvant radiotherapy. Histopathological examination showed hyper- and hypocellular areas of spindle cells admixed with myxoid areas and immunohistochemistry revealed positivity to vimentin and S100 on the basis of which the diagnosis of MPNST was made.

Imaging Characteristics

Malignant peripheral nerve sheath tumor (MPNST) is biologically an aggressive tumor of soft tissue sarcoma. MPNSTs represent 5–10% of all soft-tissue sarcomas. They correspond to malignant forms of neurofibromas and schwannomas. The main clinical symptoms of MPNST are increasing size of tumors, local or radicular pain, paraparesis, and paresthesia and/or weakness of extremities.Radiological imaging is important to determine the site and extension of the tumor, especially before surgery. Magnetic resonance imaging (MRI) is the imaging modality of choice. To some extent, MPNSTs share basic imaging characteristics with benign peripheral nerve sheath tumor, although there are some evidence of malignant transformation. Diagnosis may be challenging because there are no specific immunohistochemical or molecular markers. However, Histopathological examination is needed for definitive diagnosisThe mainstay of treatment is surgical resection. The goal of the operation is to achieve complete surgical excision of the tumor with negative (wide) margins. Together with wide surgical excision, radiation therapy offers the best outcome of local and overall survival rates.

Of all neurogenic tumors, about half are seen in the region of head and neck. Schwannomas are benign tumors of Schwann cells nerve sheath and are quite uncommon in the oral cavity, rarely occurring in the lip area. A MEDLINE search of the literature in English from 1969 to 2013 revealed only 20 documented cases of schwannomas of the lip. In the current study, authors reported a case of an intraoral schwannoma located in the lower lip. The diagnosis was established based on clinical and histopathological findings of the schwanoma which was treated by complete surgical excision. Although rare, schwannoma should be considered in the differential diagnosis of any nodule or mass in the oral mucosa.

In Pregnancy

Solitary nerve sheath tumor such as Benign schwannomas arising in the pelvic retro peritoneum is infrequently reported. Retroperitoneal location accounts for 0.3-3.2% of primary schwannomas. We report a case of benign retroperitoneal pelvic schwannoma in pregnancy that was incidentally diagnosed when it presented with Preterm premature rupture of membranes and mechanical obstruction for labour. She underwent caesarean section and delivered a healthy baby. She was evaluated in the postoperative period by computerized tomography (CT) imaging studies and CT guided fine needle aspiration cytology (FNAC) was not diagnostic. Complete surgical excision of the tumor was achieved in the postpartum period. The adjacent vascular and urinary channels sustained no injuries and she had no neurologic deficit. Histology revealed spindle cell neoplasm composed of interlacing fascicles and sheets of spindle cell with focal areas of nuclear palisading and thick walled blood vessels. Immunohistochemistry was positive for S 100 suggesting schwannoma. Retroperitoneal location of schwannomas is rare and surgery is curative. Prognosis is good, since recurrence is rare.

<p class="abstract">Schwannoma are slow growing tumours, which can arise from any peripheral nerve. 10% of schwannomas that occur in the head and neck region mostly originate from the vagus or sympathetic nervous system. Extracranial schwannomas in the head and neck region are rare neoplasm. Intraoral schwannoma are only 1% of the all head and neck tumours. Diagnosis is established by imaging studies such as magnetic resonance imaging or computed tomography, while FNAC is used to rule out other conditions. We report a rare case of lingual schwannomas generally present as a painless lump schwannoma of the tongue in a 27-year-old male complaining of asymptomatic swelling over a posterolateral surface of the tongue, treated by complete surgical excision. The diagnosis was established on the basis of clinical, histopathological, and immunohistochemical examination. We report a rare case of schwannoma over the posterolateral surface of tongue. Prognosis is good for the patient when this condition is correctly diagnosed as the condition rarely recurs after complete resection.</p>

Von Recklinghausen

Plexiform neurobroma is a rare benign nerve sheath tumor that develops in the perineurium and is often considered pathognomonic of neurobromatosis type 1 (NF1 or von Recklinghausen disease). They occur most frequently in the craniomaxillofacial region, rarely on back and extremities. These lesions are highly vascular and there is 15-20% potential for malignant transformation. Here, we present a 26-year-old female with neurobromatosis all over her body, but with a large plexiform neurobroma in the sacral region which was causing difculty in sitting and lying supine as well as disgurement of the gluteal region. Surgical excision with primary closure of the swelling was done. Histopathology ndings were consistent with neurobromatosis.

Conjunctival stromal tumor (COST) is an emerging entity with only a limited number of cases reported in the literature. In this report, we describe 2 additional cases, review the accumulative clinical and histopathological features and expand on the immunophenotypic property of this entity. COST appears to have a sporadic presentation, affecting both sexes and patients of variable ethnicity and age group and predominantly occurring on the bulbar conjunctiva as a slow-growing asymptomatic or slightly tender mass-like lesion. Histopathologically, COST is characterized by singly dispersed spindle to round cells, often with some degree of degenerative nuclear atypia, within a myxomatous to collagenous stroma. Lesional cells are characteristically positive for CD34 and vimentin, negative for S100, SOX10 and STAT6 and show a normal pattern of staining with RB1 by immunohistochemistry. The reported cases to date have shown an indolent biological behavior, reliably treated by a complete surgical excision.

Dermoid cysts of the oral cavity are rare. When they do occur, the most common site is the floor of the mouth. Intralingual dermoid cysts are even more rare, and until now, there were only 15 such reports in the English-language literature. In this article, we describe two additional cases. Magnetic resonance imaging is extremely helpful in establishing a differential diagnosis. Surgical excision is recommended to correct deglutition and speech problems. Its rarity notwithstanding, dermoid cyst should be considered in the differential diagnosis of tongue masses in the younger population.
