RESUMEN
Odontogenic myxoma is a benign, rare neoplasm of mesenchymal origin comprising of 3%-6% of all odontogenic tumors. Odontogenic myxoma occurs more commonly in the second and third decade and is more commonly seen in mandible compared with maxilla but behaves more aggressively in maxilla as it spreads through the maxillary antrum. It is usually associated with a painless swelling without any symptoms. The radiographic features are similar to other odontogenic tumors, and hence, it leads to diagnostic dilemma. Therefore, thorough knowledge regarding clinical, radiographical, and histopathological features are important to arrive at a proper treatment protocol as it shows a high recurrence rate. The aim of this paper was to present a rare case of 21-year-old male with a chief complaint of swelling in the left maxilla that infiltrated the maxillary sinus in a very short duration.
RESUMEN
INTRODUCTION: Oral submucous fibrosis is a chronic debilitating condition with potential for malignant transformation. Squamous cell carcinoma arising from a background of oral submucous fibrosis presents clinically as a distinct disease due to different etiopathogenesis. METHODOLOGY: This prospective case series describes thirty cases of oral squamous cell carcinoma (OSCC) alongside oral submucous fibrosis (OSF). Patient clinical data were recorded including type and duration of habits, site of tumor, size, histological grading and nodal status. RESULTS: A total of 76% cases were reported in males and 24% in females. A total of 73.3% cases had a history of use of gutka of which 16% used only arecanut or gutka while the remaining used gutka along with smoking and quid habits and 26.7% cases smoked tobacco products or used smokeless tobacco. Primary site of presentation was buccal mucosa and seven cases of carcinoma at retromolar trigone (RMT) altogether accounting for 66% of the cases. 53.3% cases reported were advanced tumour T4 lesions, 10% T3 lesion, 30% reported as T2 lesions and 6.7% T1 lesion. 55% of cases showed nodal involvement of different level and 46.5% cases were N0. About 60% of cases were histologically well differentiated squamous cell carcinoma. CONCLUSION: Carcinoma arising from a background of oral submucous fibrosis follows a distinct clinical presentation. Malignant transformation occurs in younger age group and with better histological grading.
RESUMEN
Ackerman's tumour or Verrucous Carcinoma (VC) is a distinct form of Squamous Cell Carcinoma (SCC). It is predominantly seen in elderly men and strongly associated with the use of tobacco. In oral cavity it occurs predominantly in buccal mucosa followed by gingiva, palate and floor of the mouth. Clinically it manifests as proliferative finger like projections resembling a cauliflower which is characteristic of its diagnosis. Histologically, papillary or verruciform surface and parakeratin plugs between the surface projections are seen with an intense infiltrate of chronic inflammatory cells in the connective tissue thus it requires enormous expertize for diagnosis. Although VC is illustrated as a benign lesion with minimum aggressive potential over a period of time it can evolve into SCC. Hence most appropriate management of Ackerman's tumour is early diagnosis and surgical excision of the lesion. With this above background, we hereby report an enticing case of verrucous carcinoma in a left retromolar trigone extending into lower alveolar ridge in a 52-year-old male patient.
RESUMEN
INTRODUCTION: Osteoporosis is a regressive change which occurs in the bone and it is seldom diagnosed before the occurrence of fractures. Hence, determination of mandibular bone density is of paramount importance for the detection of this silent disease. AIMS AND OBJECTIVES: The purpose of this study was to evaluate the influences of gender and age on the radiomorphometric indices and to assess the differences in the various indices, if any, between digital and analog radiographs. MATERIALS AND METHODS: Two hundred and fifty six panoramic radiographs (128 digital and 128 analog) were obtained and they were grouped into 8 age groups which were between 21 to 60 years with 5 year intervals between them, with equal sex distributions. The mandibular cortical index (MCI), mental index (MI) and panoramic mandibular index (PMI) were analyzed. RESULTS: C2 and C3 categories of MCI increased as age advanced in females. MI showed a significant difference in genders and MI Values decreased from younger to older females. PMI (p<0.05) was significant for both the genders. CONCLUSION: This study showed that MCI, MI and PMI indices were useful for identifying patients with low skeletal bone mineral densities (BMD) or osteoporosis and that digital panoramic radiographs were better than analog radiographs for measuring the indices.
RESUMEN
PURPOSE: To determine the prevalence of oral mucosal lesions associated with tobacco among patients visiting the dental hospital. MATERIALS AND METHODS: A selection of 1525 patients visiting the Department of Oral Medicine and Radiology were interviewed regarding tobacco habits. Examination of the oral cavity was performed by trained examiners under good illumination using diagnostic instruments. Oral mucosal lesions were diagnosed based on the clinical features. RESULTS: The patients were divided into groups based on their tobacco habits. Out of 1525 patients, 359 patients (23.5%) had the habit and 265 (73.8%) of them had oral mucosal lesions. Leukoedema was the most prevalent lesion. Leukoplakia was found in 3.5% of the patients. Malignancy was found only among chewers. CONCLUSION: Nearly three-quarters of the patients with the tobacco habit had oral mucosal lesions. This emphasises that routine examination of oral mucosa is important and that the patients must be motivated to quit this harmful habit.
