Histological Aspect

The ameloblastoma is a locally aggressive odontogenic tumour that has high recurrence rates. It rarely presents a histological aspect similar to the odontogenic keratocyst, because of the presence of keratinised areas. This study aimed to report a case of ameloblastoma in the mandible, diagnosed and treated incorrectly as an odontogenic keratocyst because of unusual macroscopic characteristics and rare histological aspects that impaired a correct diagnosis. Case report: A 57-year-old female patient, presenting an asymptomatic lesion at the left mandibular angle, was treated by incisional biopsy and decompression. The histological sections showed an aspect suggesting odontogenic keratocyst. At the 3-year postoperative period, the patient returned with a new lesion on the left side of the mandible and was then subjected to curettage. The histological sections showed a pattern of ameloblastoma and, because of this, the patient remained with a 6-month follow-up. At the 4-year postoperative period after the second operation, the patient returned with a new recurrence. The biopsy showed an ameloblastoma and the patient was submitted to mandibular resection and reconstruction as treatment. After the final procedure, the recovery was uneventful and the patient is now undergoing a postoperative period of four years, without recurrences. Conclusion: This case highlights the importance of carrying out a proper biopsy and an adequate examination by a specialised professional, because of the possibility of atypical lesions occurring restricted to the head and neck region.

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.

AbstractObjective:We present the first reported case of primary carcinoid tumour of the nasal septum.Method:Case report of our experience of a carcinoid tumour of the nasal septum. We discuss our clinical, radiological and pathological findings.Result:An 83-year-old woman presented with a history of left-sided nasal blockage. Clinical examination showed a unilateral, left-sided nasal polyp. Further imaging and histological analysis confirmed this to be a carcinoid tumour. Carcinoid tumours outside the gastrointestinal tract are rare. There have been reports of carcinoid tumours in the head and neck region, but no published cases occurring in the nasal septum. Our management involved wide surgical resection with regular follow up to monitor for recurrence and for the development of carcinoid syndrome. Four years from initial presentation, the patient remained free of the primary tumour and had displayed no signs or symptoms suggestive of carcinoid syndrome.Conclusion:To the authors' best knowledge, and after searching the world literature, the presented case represents the first report of primary carcinoid tumour of the nasal septum. Despite its rarity, this tumour should be considered as part of the differential diagnosis, as timely recognition and intervention are critical for successful treatment.

Rare Case Report

Background: Osteosarcoma is a malignant neoplasm that occurs most often in long bones, with the head and neck region being rarely affected, accounting for less than 1% of all cancers in this region. Objective: To report a rare case of a large-extension osteosarcoma with emphasis on its clinical and diagnostic aspects. Case presentation: A 43-year-old woman presenting an intraoral exophytic lesion with involvement of other maxillofacial structures, such as nostril, zygoma and orbit. Despite the initial clinical diagnosis of actinomycosis, an incisional biopsy confirmed the histopathological diagnosis of osteosarcoma, showing a wide morphological variety. Conclusion: This case highlights the importance of clinical and histopathological findings for the correct diagnosis of osteosarcoma. Moreover, it shows that, although surgical resection is the primary treatment for this neoplasia, depending on the extent of the tumor and its proximity to vital anatomical structures, the most appropriate conduct is not always feasible.

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:

AbstractGrisel syndrome is a rare condition characterised by atlanto-axial subluxation following an inflammatory process in the head and neck region. It occurs more commonly in children and usually presents with cervical pain and torticollis, in addition to symptoms of the primary infection. We present the case of an asymptomatic 78-year-old man who was incidentally found to have atlanto-axial subluxation on a routine follow-up computed tomography scan, three months following successful treatment of a skull base infection. This case emphasises the importance of appropriate follow-up imaging for patients with skull base infections, even if they respond clinically to medical treatment.

Hemangiomas are the most common tumor of infancy, and the vast majority occur in the head and neck region. In children, laryngeal hemangiomas typically occur below the level of the true vocal folds, in the region of the subglottis, and other sites are exceedingly rare. We present four cases of hemangiomas located in the postcricoid region of the hypopharynx. Because of the location of these lesions, children may present with obstructive symptoms such as dysphagia, intermittent aspiration, hypersalivation, or recurrent respiratory infections. Clinical diagnosis is relatively easily made with flexible laryngoscopy, as the lesions have a propensity to enlarge with crying or straining. When these patients are examined under general anesthesia in a relaxed state, however, the lesions are typically much smaller, and can even go unnoticed. Unlike other reported cases, the postcricoid hemangiomas in our patients were not causing any symptoms and were simply incidental findings. Thus, we believe that the true incidence of postcricoid hemangiomas is likely higher than reports suggest. To our knowledge, we report the longest follow-up (6 years) of a patient with a postcricoid hemangioma and are the first to describe the natural course of such a lesion.

<p class="abstract">Epidermoid cysts are frequently encountered cutaneous cysts. They are mostly tiny and benign swellings. But rarely they can grow huge in size and malignant transformation can also occur occasionally. Cosmetic disfigurement is also another important concern especially in head and neck region. We report a case of earlobe epidermoid cyst, a location where very few cases have been described in the literature. The cyst was completely excised and the wound was closed with nylon 4/0. Histopathological examination confirmed the diagnosis of an epidermoid cyst. The patient did not have any signs of recurrence even after six months postoperatively. Due to the possibility of malignant transformation and to ensure correct diagnosis, we consider that histopathological examination is necessary for all cysts although the clinical diagnosis could be enough.</p>

Leiomyosarcoma (LMS) is a rare mesenchymal malignancy, of which 3–10% of cases occur in the head and neck region. We report a 22-year-old woman who was referred to the University Hospital of Siena, Italy, in 2016 with an ostensibly benign asymptomatic lump on the mandibular gingiva. The lesion grew rapidly, causing otalgia in the right ear. An excisional biopsy was performed and primary LMS was diagnosed histologically. Subsequently, the patient underwent radical re-excision of the perilesional mucosa, a partial bone resection and the extraction of four teeth. No recurrences or metastases were detectable at a 20-month follow-up. This report discusses the differential diagnosis of LMS with regards to other benign and malignant lesions and reviews the recent literature on primary and secondary oral LMS. Due to its innocuous clinical features—including its asymptomatic nature and presentation at a young age—this aggressive malignancy can go undetected; therefore, an early histopathological diagnosis is crucial.

<p class="abstract">Lipomas are uncommon in the head and neck region and rare in the retropharyngeal space. Lipoma of the retropharyngeal space may cause aerodigestive tract obstruction presenting as dyspnea and or dysphagia. The presenting symptoms will depend on the size and site of the lipoma in the retropharyngeal space. We present the case of a 57 years old male with 6 months’ history of progressive dysphagia to solid foods only and no positive sign on clinical examination. The barium swallow was normal. The computed tomography (CT) scan showed a moderate-sized homogenous mass of fat density in the hypopharyngeal section of the retropharyngeal space. Diagnosis of dysphagia caused by retropharyngeal lipoma was made. This was surgically excised via the trans-cervical route with no complications, complete resolution of symptoms, and no recurrence 2 years after on follow-up. In the dysphagia of unknown cause, retropharyngeal space lipoma should be considered.</p>
