“…Our study is consistent with the result of literature review which reported that radicular cysts are most common odontogenic jaw cyst and constitute more than 50% of jaw cysts and maxillary ameloblastoma accounting for 9-10% of all odontogenic tumors. 2,12 Dermoid cyst and sebaceous cyst are considered rare lesion in nasomaxillary area. Inverted papilloma is a neoplasm that is histopathologically benign but clinically malignant lesion.…”

Background: A wide spectrum of lesions may present as nasomaxillary swellings ranges from benign to malignant lesions including fungal sinusitis and fibro vascular lesions example: JNA (Juvenile nasopharyngeal angiofibroma) and Inverted papilloma. Many Pathologies ranging from benign to malignant tumors may mimic a simple Nasomaxillary mass. It is diagnostic challenge to determine pathology behind it. A detailed clinical evaluation with nasal endoscopy and relevant pre-operative investigations including radiological imaging and histopathological examination is essential to reach up to final diagnosis. The aim of the study was to do clinicopathological evaluation of patients presenting with nasomaxillary swelling and correlation of clinical, radiological and Histopathological findings.Methods: This was a prospective observational study on 50 nasomaxillary swelling patients who are presented in the Department of ENT and Head and Neck Surgery of N.S.C.B. MCH Jabalpur, a tertiary care Hospital, between March 2018 to August 2019. A detailed history taking and clinical examination with nasal endoscopy and relevant preoperative investigations including CECT Nose and PNS and histopathological examination was done in all patients.Results: 50 Nasomaxillary swelling patients were selected for this study. 30 patients were male and 20 were females. Ages of patients were varied from 12 years to 72 years. 23 patients (46%) were malignant and 27 (54%) were benign. Histopathological examination results shows benign lesions like JNA (6 cases), fungal sinusitis (6 cases), dermoid cyst (1 case), inverted papilloma (3 cases), sebaceous cyst (1 case), jaw lesions (10 cases), (odontogenic like radicular/ infected cyst, dentigerous cyst, cystic ameloblastoma and non-odontogenic like fibrous dysplasia) and malignant lesions like SCC (squamous cell carcinoma) (12 cases), spindle cell sarcoma (2 cases), undifferentiated carcinoma (3 cases), adenocarcinoma (3 cases), adenoid cystic carcinoma (1 case), Invasive pleomorphic sarcoma (1 case) and malignant melanoma (1 case). SCC was most common lesion f/b JNA and fungal sinusitis. Well differentiated SCC was most common histological type (10 out of 12 cases of SCC). Most common symptom was nasal obstruction (66% cases) f/b epistaxis (52% cases) but epitasis was most common symptom among malignant and JNA cases. In 6 cases (3 JNA, 1 inverted papilloma, 1 malignancy and 1 radicular cyst) radiological diagnosis were not correlated with histological findings.Conclusions: Most our cases were malignant nasomaxillary lesions followed by fungal sinusitis and JNA. Most patients presented in advanced stage of disease so rapidly evaluation including nasal endoscopy should be done. CECT scan is essential to determine tumors extent and bony lesions. All patients should undergo hisotopatholigical examination. The final diagnosis should be made on the basis of clinical, radiological and histopathological findings.

“…It is generally accepted that only 20% of ameloblastomas occur in the maxilla, although some reports indicate an incidence as low as 1% in the maxilla and of those 47% occur in the molar region, 15% in the antrum and the floor of the nose, 9% in the premolar areas, 9% in the canine regions and 2% in the palate. 8 Ameloblastoma occurs over a broad age range; cases have been reported in children younger than 10 years through elderly adults older than 90. The average age at diagnosis consistently is reported in the age range of 33 to 39, and most cases cluster between ages 20 and 60 years, 9 as in our case.…”

“…Sometimes, invasive maxillary ameloblastomas with extension into the orbit, frontal sinus, skull base, middle cranial fossa and petrous apex have resulted in the death of the patient. 8 Patients with ameloblastoma most commonly present with chief complaints of swelling and facial asymmetry. Although, the swelling is typically asymptomatic, pain is an occasional presenting sign.…”

“…Maxillary ameloblastomas are more difficult to treat because of the combination of the well vascularized, fragile, cancellous maxillary bones, presence of the paranasal sinuses, nasal and orbital cavities which readily facilitates tumor spread to the zygomatic bone, cranial base and paracranial structures and the pterygomaxillary fissure. 8 These are usually treated by resection with 10 to 15 mm safety margin of healthy bone. This may include resection of the alveolar ridge, hard palate and maxillary sinus and the lateral nasal wall.…”

Ameloblastoma is a benign but locally aggressive odontogenic tumor. The knowledge about this tumor is gaining greater importance because of its emerging variants. It is very essential to know the clinical, radiological and histopathological features of all the subtypes of ameloblastoma along with their behavioral and prognostic characteristics. Worldwide, maxillary ameloblastoma is rare, but its late detection renders adequate treatment difficult. Majority occur in the mandible with about 5 to 20% occurring in the maxillary bone. Here, we report a case of follicular ameloblastoma of the anterior maxilla in a 60-year-old male.

INTRODUCTION:Nasal cavity and paranasal sinuses present a range of non-neoplastic and neoplastic lesions by virtue of their anatomic and histologic diversity. Although a presumptive diagnosis is arrived at based on presenting symptoms and imaging techniques, histopathology is the mainstay for definitive diagnosis and management of sinonasal lesions. AIMS AND OBJECTIVES: To study the incidence, mode of presentation and histologic types of sinonasal lesions in surgical pathology material. SETTING AND DESIGN: Retrospective retrieval of all sinonasal lesions and histopathologic analysis. MATERIALS AND METHODS: All sinonasal lesions, biopsied or excised over a period of three years between May 2010 and May 2013, were studied. The lesions were classified as non-neoplastic or neoplastic. Neoplasms were further categorised as benign and malignant. The histology was correlated with clinical features. Special stains and immunohistochemistry were done wherever indicated. RESULTS: In three years, sixty-one sinonasal lesions were reported, representing 0.47% of all surgical pathology specimens. Out of sixty-one cases, forty-one (67.21%) were non-neoplastic and twenty (32.79%) were neoplastic. Sinonasal lesions were common in the second and third decades of life, with male predominance. Among the non-neoplastic lesions, inflammatory polyps were the most common (80.49%). Among neoplasms, benign tumors (60%) were more frequent than malignant tumors (40%). Angiofibroma (6 cases-50%) was the commonest benign neoplasm and squamous cell carcinoma (4 cases-50%) was the commonest malignant neoplasm. CONCLUSION: Non-neoplastic and neoplastic lesions in the sinonasal region have similar clinical manifestations. Categorization based on histopathology is necessary for differential diagnosis, management and prognosis of these uncommon lesions. KEY WORDS: nasal cavity, paranasal sinuses, non-neoplastic, neoplastic, histopathology INTRODUCTION:The nasal cavity and paranasal sinuses form a functional unit of specialized tissues, each with its own aberrations. 1 They share many pathologic processes, most of which are inflammatory. 2 Exposure to various influences like chemical irritants, antigenic stimulants, and mechanical trauma results in deleterious consequences, including formation of tumors and tumorlike conditions. 3 Inflammatory polyps are a common cause of nasal obstruction, with a prevalence of 4% in the general population. 4 Benign tumors are relatively common, but malignant neoplasms are rare, accounting for 0.2-0.8% of all carcinomas and only 3% of those in the upper aero digestive tract. 5 Most of these lesions present as polypoid masses, making it difficult to distinguish nonneoplastic polyps from polypoid neoplasms clinically. 6 Histopathologic diagnosis is therefore mandatory for appropriate management and prognosis of sinonasal lesions. This study was undertaken to classify sinonasal lesions based on histopathology and to analyze their age and sex distribution.
