Slow Growing

Neurilemmomas are slow growing, benign neoplasms of neural crest Schwann cell origin. They arise from any peripheral, spinal or cranial nerve except the olfactory and optic. Presentation is usually asymptomatic but focal neurological signs and symptoms may be associated with nerve compression. With approximately one third of all documented cases presenting in the head and neck region, we report a case of a submandibular neurilemmoma misdiagnosed pre-operatively. The diagnostic difficulties are discussed and the current literature reviewed. Thiscase highlights the importance of inclusion of nerve sheath tumours in differential diagnoses of soft tissue lesions in the head and neck.

<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>

Nerve Of Origin

Introduction. Schwannomas are tumors of neurogenic origin, that arise from Schwann cells which surround peripheral, cranial and autonomic nerves. Schwannomas account for only 5% of all benign soft tissue tumors, and 25-45% of extracranial schwannomas are present in the head and neck region. They are usually classified according to the nerve of origin and the site within the head and neck. Case report. We presented extremely rare extracranial localizations of schwannomas and discussed about diagnosis and management of these tumors. Conclusion. Schwannomas are slow-growing tumors and late symptoms appearance may cause a delay in diagnosis and treatment of patients with these tumors. An appropriate diagnostic protocol is indispensable tool in performing a differential diagnosis of malignant from benign lesions. Choice of surgical approach depends on schwannomas localization.

Unusual Lesion

Primary chondrosarcomas of the head and neck region are exceedingly rare neoplasms. These lesions have clinical and histologic characteristics that make them difficult to discern from benign chondromas. Additionally, they may arise from the periosteum, making it even more difficult to distinguish them from osteosarcomas. We present a patient with a periosteal chondrosarcoma of the maxilla. Characteristic radiologic and histologic findings associated with this lesion are described. This is the first reported case of such a lesion in the maxilla, as previous reports of periosteal chondrosarcomas have involved long bones. The diagnostic dilemma posed by this extremely unusual lesion is discussed, as well as treatment options.

Rare Diagnosis

Schwannomas/ neurilemmomas are benign tumors of nerve sheath arising from Schwann cells that form myelin sheath around peripheral nerves. They are usually solitary, slow growing and encapsulated lesions. Head and neck are the common sites. We report a case of a 38 years old Nepalese female who had presented with a solitary asymptomatic, slow growing nodule on the left side of the chin for the last three years. Dermoscopy of the lesion revealed arborizing vessels with brownish pigmentation overlying a whitish to pinkish background. Complete excision of the lesion was performed. Histopathological evaluation of the lesion revealed schwannoma. Though schwannomas are a rare diagnosis, they should be considered as a differential diagnosis of any unilateral, asymptomatic, slow growing nodule in the head and neck region. Dermoscopy is a useful tool which helps to differentiate schwannoma from other lesions. Histopathology is the gold standard for diagnosis and the treatment of choice is surgical excision.

ABSTRACT Context: Extra-nasal rhinosporidiosis is not uncommon in endemic region like India. Clinical presentations of extra-nasal rhinosporidiosis lesion often lead to diagnostic dilemma. Cytology can help in the preoperative diagnosis of such lesions. Aims: The aims of our study were to find the clinico-pathological presentation of extra-nasal rhinosporidiosis and to evaluate the role of cytology in diagnosing these lesions preoperatively. Settings and Design: Fine-needle aspiration cytology is often used for preoperative diagnosis of sub-cutaneous lesions of the head and neck region. This retrospective study was designed to include the cytologically diagnosed cases of rhinosporidiosis and to compare with final histopathology of the lesions. Materials and Methods: A total of 21 cases of extra-nasal rhinosporidiosis were diagnosed in our study period of 18 months. Cytology was approached in 17 cases and 16 cases were diagnosed as rhinosporidiosis, which were included in the study group. Twelve cases were sampled by fine-needle aspiration and four cases by scrap technique. Histopathological confirmation was possible in all cytologically diagnosed cases. Results: Head and neck region were involved in 15 cases and only one case was on the skin of right upper arm. Orbital region was the most common extra-nasal site of involvement. Most of the cases (13 cases, 81.25%) belonged to the age group of 11-30 years. All cytologicaly diagnosed cases of rhinosporidiosis were concordant with histopathology. Only one false-negative case was cytologically diagnosed as suppurative inflammatory lesion. Sensitivity and specificity of cytology in diagnosis of extra-nasal rhinosporidiosis were 94.11% and 100% respectively. Conclusions: Extra-nasal rhinosporidiosis is an important differential diagnosis of nodular, polypoid mass of head-neck-face region. Cytology can be used as an important tool in preoperative diagnosis of extra-nasal rhinosporidiosis.

The Way

One challenging feature of head and neck pathology is that a dizzying array of sarcomatoid lesions occurs here ranging all the way from reactive to malignant and very aggressive. This makes accurate diagnosis critical. These lesions are quite diverse with great clinical and biological heterogeneity. Some are malignant while many others are benign or simply reactive in nature. For example; at mucosal sites, a well known lesion is spindle cell carcinoma (SpCC), which are overtly malignant, and the differential diagnosis then includes a number of different malignant spindle cell lesions. However, there are several benign or even non-neoplastic lesions that can sometimes be difficult to discern from SpCC, e.g. Nodular fasciitis, Proliferative myositis, Cellular schwannoma, Benign fibrous histiocytoma, Carcino sarcoma, Sarcomatoid melanoma. Fracture callus, etc. Aim of Study: There is a diagnostic challenge to the oral pathologists to differentiate dizzying array of sarcoma like lesions from other similar microscopic simulates ranging all the way from reactive to malignant and very aggressive. This article aims to review the sarcomatoid lesions of the head and neck region with emphasis on differential diagnosis histologically and immunohistochemicaly.

Schwannomas are relatively rare benign neoplasms of neurogenic origin from the neural sheath of peripheral nerves occurring more commonly in the head and neck. Mandibular bone is the commonest site of occurrence of these nerve lesions. Radiographically, intraosseous schwannoma of mandible is very difficult to differentiate from other bony pathologies such as neurofibroma, ameloblastoma, fibrous dysplasia, myxoma, central giant cell lesion, or periapical lesion, so it should be included in the differential diagnosis of lower jaw swelling. Schwannoma as a pathologic entity was first reported in 1910 by Verocay. Schwannoma (also known as neurinoma, neurolemmoma, neurilemmoma, perineural fibroblastoma, and peripheral nerve sheath tumour) is a rare, slowgrowing, benign neurogenic neoplasm that originated from Schwann cells. Schwann cells cover myelinated sheath of nerve fibres.1 These intraosseous schwannomas account for not more than 1 % of the central neoplasms. More than one third of all schwannomas are found in the head and neck region. 2 Most of these originate from the lower cranial nerve and sympathetic nervous system. Schwannomas from the upper cranial nerves such as trigeminal nerve and its branches are less common. Other commonly reported sites include the vertebra, clavicle, ribs, sacrum, humerus, ulna radius, etc. This painless slow-growing neoplasm may develop at any age.
