Common Malignant Tumour in Oral and Oropharyngral Lesion

Background with Objective: A variety of non-neoplastic and neoplastic lesions can involve the oral cavity and oropharyngeal region. In 1971 WHO classified oral lesions into malignant tumours, benign tumours and tumor like lesions. The aim of this study was to assess the common types of malignant tumor in oral and oropharyngeal lesion. Methods: This descriptive cross-sectional study was carried out among 98 patients presenting with malignant tumor in oral cavity and oropharynx at Pathology department for histopathology, Dhaka Medical College Hospital, Dhaka, from January 2016 to December 2017. Purposive sampling method was followed. Statistical analysis of the results were obtained by using window based computer software devised with Statistical Packages for Social Sciences (SPSS-20.1). Results: Female patients (55%) suffering from more malignant tumor in oral cavity than male patients (45%). Most of the patients belonged to 41-50 years (32%). 99% patients had multiple personal habits while remaining 1% patient reported no personal habit. The most common personal habit is betel leaf and nut with jorda, sad and gul followed by tobacco smoking. Most common malignant tumors were squamous cell carcinoma – G-I (58%) and squamous cell carcinoma – G-II (31%) in oral and oropharyngeal lesion. Most of the patients (81.6%) presented with ulceration and 18.4% patients had growth/mass. Only 27.55% patients had history of pain in tumor. Buccal mucosa were the common site (42%) for malignant tumor in oral and oropharyngeal region. Conclusion: Squamous cell carcinoma G-I were more common malignant tumor in oral and oropharyngeal lesion.
