Schwannomas are benign nerve sheath tumors. These arise from Schwann cells of the neural sheath. Intra oral region is a relatively uncommon site of these tumors. They are solitary, slow growing, smooth surfaced, usually asymptomatic, and encapsulated tumors, about 25% of all schwannomas are located in the head and neck, but only 1% show intraoral origin. A 22-year-old female came with dysphagia since, 3 years. FNAC was not feasible and so excision biopsy of the lesion was performed. Histopathology revealed schwannoma like picture and it was confirmed with diffuse S-100 positivity on immunohistochemistry. Hence, finally confirming schwannoma of the oropharyngeal region. Schwannomas can be found anywhere in the body but a quarter of all occur in the head and neck region. Intraorally its percentage is only 1% with tongue being the commonest. Pharyngeal presentations of schwannoma are rare. Schwannomas are benign tumors having excellent prognosis. Basically, this case report is important as these very rarely occur in the oropharyngeal region and it’s a must to consider them in the differential diagnosis of lesions at this site.

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.

Mesenchymal Neoplasm

Background: Lipoma is a benign tumor composed of mature white adipocytes and it is the most common soft tissue mesenchymal neoplasm. It is well separated from the surrounding tissues by a thin fibrous capsule. Lipomas occur in any part of the body that has fat tissues. 13% of such tumors are seen in the head and neck region. Angiofibrolipoma is a variant of lipoma with a prominent vascular component: Angiofibrolipoma is a subtype of lipoma composed of fibrocytes, capillaries and mature adipocytes. These tumors occur in the forearm, followed by trunk and in the extremities of young individuals. Its occurrence is very rare in the head and neck region. They are benign tumors that cause symptoms depending on their size and location. It is important to bear in mind this clinical entity in the differential diagnosis of the swellings that arise in relation to the tendon sheath. Patient and method: A patient with a recurrent swelling in the right wrist region was taken up for surgery with a clinical diagnosis of a fibrous tumor. Result: Histopathological diagnosis revealed the tumor as a rare variant of lipoma. Conclusion: This report highlights the fact that angiofibrolipoma should be considered in the differential diagnosis of swellings in different regions of the body. Keywords: Angiofibrolipoma, Tendon sheath, Synovial membrane, Soft tissue tumors.

Adenomatoid tumors are responsible for 30% of all paratesticular masses. These are usually asymptomatic, slow growing masses. They are benign tumors comprising of cords and tubules of cuboidal to columnar cells with vacuolated cytoplasm and fibrous stroma. They are considered to be of mesothelial origin supported by histochemical studies and genetic analysis of Wilms tumor 1 gene expression. Excision biopsy is both diagnostic and therapeutic procedure. The main clinical consideration is accurate diagnosis preventing unnecessary orchiectomy. Diagnostic studies include serum tumor markers (negative alpha fetoprotein, beta HCG, LDH) ultrasonography (hypoechoic and homogenous appearance) and frozen section.

<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>

Introduction: Adenoid cystic carcinoma is a rare salivary gland malignancy that can occur in any part of the body, its clinicopathologic features are scarcely reported in locoregional literature. Therefore, in this study we aimed to evaluate the clinicopathologic features of adenoid cystic carcinoma in our population and to determine the association of age and site of its occurrence with histologic pattern and perineural invasion. Methods: We retrospectively analyzed 30 cases of adenoid cystic carcinoma that underwent surgical resections or biopsies from March 2009 to February 2020 at Liaquat National Hospital and Medical College, Karachi. Clinical and histopathological parameters including age, site, histological pattern and perineural invasion were determined and association between different parameters was analyzed. Results: Mean age of the patients was 30 + 16.1 years. Cribriform pattern was most common histologic pattern (63.3%) while head and neck region was the most common site of occurrence (83.3%). Perineural invasion which is one of the most important prognostic factors in adenoid cystic carcinoma was present in approximately half of the patients (46.7%). No significant association of age and site was found with histologic pattern and perineural invasion. Conclusion: Adenoid cystic carcinoma is a rare malignancy most commonly occurring in head and neck region with a high frequency of perineural invasion. No significant difference of histologic pattern and histologic prognostic parameter like perineural invasion was noted at different ages and different sites in our study.

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.

AbstractPerifollicular fibroma (PFF) is a rare proliferative lesion originating from the perifollicular connective tissue sheath. It may be congenital or acquired manifesting as skin colored to pink, asymptomatic papules of 1-5 mm in size. They are commonly distributed in the head and neck region. Multiple PFFs may be associated with internal malignancy or as a part of Birt-Hogg-Dube syndrome. Histopathology serves as an essential tool in clinching the diagnosis. Herein we report a case of giant congenital PFF.
