<p>Schwannomas or neurilemmomas are benign tumors of the nerve sheath that are single, well encaspsulated, bening and arise from the perineural schwann cells. They may arise either in central or peripheral nerves. Approximately 25–45% of all schwannomas are present in the head and neck region. The overall incidence of intra-oral schwanommas is 1% with most common site being tongue followed by buccal mucosa and lastly lip and gingival. Here we present a case report of lower lip schwanomma arising from mental nerve. On physical examination, a smooth globular swelling was present in the lower lip on right side, 2 cm × 3 cm in size and of firm, non-tender in character with regular margins. The patient underwent surgery and the lesion was excised intraorally with sublabial incision. Final pathological diagnosis was made as “schwannoma.” The patient has been following up for 6 months and there is no evidence of any recurrence. High index of suspicion is required and Schwannoma should be considered as a differential diagnosis in oral cavity bening lesions. The final diagnosis is based on histopathology report and immunohistochemical analysis. The treatment of these tumors is complete resection. The prognosis of such cases is extremely good, without any recurrence.</p>

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.

First Case

Schwannomas are benign tumors arising from Schwann cells of the sheaths of peripheral nerves. Although vagus nerve and sympathetic chain composed of sympathetic fibers is one of the most common sites of schwannomas in extracranial head and neck region, many cases of origin unknown schwannomas were reported. We report an unusual rare case of a submandibular gland schwannoma in a 67-year-old lady, who was successfully treated by surgical excision with no cranial nerve deficits and complete resolution of the symptoms postoperatively. In this report, we establish a rare findings of schwannoma of the submandibular gland and to the best of our knowledge, this is the first case-report of schwannoma of submandibular gland reported from a tertiary hospital in the east coast of Malaysia.International Journal of Human and Health Sciences Vol. 02 No. 01 Jan’18.

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

Context.—Myeloid sarcoma of the head and neck region can pose diagnostic challenges because of the low frequency of myeloid sarcoma and the potential for tumors of almost any lineage to occur in the head and neck. Objective.—To study the clinicopathologic and immunohistochemical characteristics of myeloid sarcoma in the head and neck region and to review the differential diagnosis. Design.—We searched for cases of myeloid sarcoma involving the head and neck region for a 24-year period at our institution. The medical records and pathology slides were reviewed. Additional immunohistochemical stains were performed. Results.—We identified 17 patients, age 17 to 85 years. Most tumors involved the oral cavity. Myeloid sarcoma was the initial diagnosis in 9 patients (53%); the remaining 8 patients (47%) had a history of bone marrow disease. Immunohistochemical analysis using antibodies specific for lysozyme, CD43, and CD68 were highly sensitive for diagnosis but were not specific. By contrast, assessment for myeloperoxidase in this study was less sensitive but more specific. We also used antibodies specific for CD11c and CD33 in a subset of cases, and these reagents seem helpful as well. Conclusions.—The clinical presentation of myeloid sarcoma involving the head and neck, particularly the mouth, is often nonspecific, and a high degree of suspicion for the possibility of myeloid sarcoma is needed. Immunohistochemistry is very helpful for establishing the diagnosis.

Schwannomas or neurilemmomas are the most common benign tumors of the neural sheaths of the peripheral nerves. Incidence of these tumors in the hand accounts to 0.8-2%. The majority of them appear as an isolated grown mass along the route of the nerves. Peripheral nerves benign tumors present many difficulties concerning the clinical diagnosis and only histopathological evidence provides the final diagnosis. In this case study, we present a 45 year old man with a grown asymptomatic mass on the volar surface of right hand (hypothenar) remained for two years and impinging the skin of the hand only the last months. Initial MRI results diagnosed the mass as gaglion cyst. Histopathological examination revealed a schwannoma. We present this case as a rare manifestation of a schwannoma in hypothenar area of the hand. A literature review of diagnoses and therapeutic management is also presented.

Adnexal Tumors

Background: Adnexal skin tumors are relatively rare and present diagnostic difficulties in view of the endless morphological spectrum, complex nomenclature and incomplete knowledge of their histogenesis. Since pathologists encounter these lesions rarely, accurate sub classification of these can be challenging. This study intends to study skin adnexal tumors with eccrine and apocrine differentiation with emphasis on their histomorphology.Materials and Methods:The present study is a five year retrospective study with comprehensive analysis of 40 cases of adnexal tumors of skin in a tertiary center in Karnataka, South India. These tumors were reclassified and subtyped according to WHO classification of skin tumors, 2006.Results and analysis:Out the 62 cases of adnexal tumors studied, 40 were tumors with eccrine and apocrine differentiation (77% benign and 23% malignant). Hidradenoma was the most common tumor comprising 37% of all tumors and 45% of the benign tumors followed byspiradenoma, cylindroma and chondroidsyringoma respectively. Head and neck region was the most common site of occurrence, and seventh decade was the most frequent age group of presentation. A definite female preponderance was noted. Pagets disease of the breast was the most common malignant tumor in this group comprising (10%). Conclusion: Histopathology is considered the gold standard in the diagnosis of these tumors and so a clear knowledge of the clinical presentation and histomorphology of these tumors is essential to make a correct diagnosis. A diagnostic logarithm based on histomorphology provides a logical approach in the subclassification of adnexal tumors.DOI:

Most had cervical lymphadenopathy (35), 9 had laryngeal, 7 tuberculous otitis media, and one patient each of PNS, oropharyngeal and retropharyngeal involvement. 8 patients had pulmonary TB, 2 had Potts spine, and 5 gave history of previous TB. FNAC was effective in nodal disease, PPD test positive in 20% and HPE was used to make the diagnosis in other types.</p><p class="abstract"><strong>Conclusions:</strong> TB is re-emerging as a significant cause of morbidity. Diagnosing EPTB requires high index of suspicion. Cervical lymphadenopathy is the commonest presentation, followed by larynx, and then ear. FNAC is a reliable and convenient way to diagnose lymphadenopathy. Hitopathological examination needed for confirmation, and for other sites. Further investigations are needed to exclude pulmonary or systemic TB. All patients should be categorised into proper category of anti-tuberculous treatment (ATT) and treated according to ATT regimen.</p>

AbstractRhabdomiomas are rare mesenchymal benign tumors of striated muscle origin. Setting aside the cardiac (most atrial) rhabdomiomas typically associated to neurocutaneous syndromes (tuberous sclerosis), extracardiac rhabdomyomas appear clinically as a subcutaneous nodule or as a submucosal polypoid lesion. Among them, three main histologic subtypes can be differentiated on the basis of the degree of tumor differentiation: 1) fetal rhabdomioma, usually diagnosed during childhood and almost exclusively located in the in the head and neck region with rare reports in other locations; 2) adult rhabdomioma; and 3) genital rhabdomioma, reported to occur in the lower genital tract of young and middle-aged women and, exceptionally, in children (5).

AbstractAspirates were obtained from 142 masses in 120 patients who presented with palpable swellings in the head and neck region. 120 specimens (84.51 per cent) were adequate for diagnostic purposes and the remaining 22 (15.49 per cent) were unsatisfactory. Final diagnosis was based on resection histology in 87 cases and close clinical follow-up in 55 patients. The overall sensitivity and specificity including unsatisfactory aspirates was 81.37 per cent and 93 per cent respectively (if the technically inadequate specimens were deleted 98.81 per cent and 94.44 per cent). In comparison with the final diagnosis typing of malignant tumours was possible in 58.33 per cent. The correct diagnosis was made in 63.89 per cent of benign lesions.
