Traumatic ulcerative granuloma with stromal eosinophilia (TUGSE): a rare self-healing oral mucosal lesion

Background: Oral mucosal lesion (OML) is defined as any abnormal alteration in color, surface aspect, swelling, or loss of integrity of the oral mucosal surface. Some oral mucosal lesions are benign and require no treatment but some may present with significant pathology. Several oral potential disorders frequently progress into malignancy Objective: The present study was carried out to assess the pattern of various oral cavity lesions of patients attending in a regional tertiary care hospital in northern area of Bangladesh. Materials and Methods: This prospective cross-sectional study was carried out in the Department of Dentistry in collaboration with department of Pathology of Khwaja Yunus Ali Medical College and Hospital, Sirajgonj, Bangladesh during the period of one year from December 2016 to December 2017. An elaborate schedule was prepared before undertaking the study. A total of 73 patients in the Dental OPD of the hospital presenting with oral lesion for more than 3 weeks were randomly selected. An incisional biopsy was taken from all patients and histological examinations were done. The collected data were analyzed using SPSS (V-20) and MS Excel. Results: Most common site of oral lesion is Buccal Mucosa (36.99%), then supraglotic region (26.03%), lower lip 6.85%, gingiva 5.48%, anterior palate and oral flor 4.11% each. Most of the lesion was Squamous cell carcinoma (58%), then lichen planus, leukoplakia, inflammatory lesion, pyogenic granuloma and verrucous carcinoma, each of them was around 5% of lesion. Conclusion: The epidemiological data on the prevalence of oral lesion is an important determinant in planning appropriate levels of services and further studies are required to provide accurate estimates of the treatment need in Bangladeshi population with oral lesion.

Introduction: . The oral mucosa performs essential protective functions that affect the general health of the patient. Oral lesions can cause discomfort or pain that interferes with mastication, swallowing, and speech. Aim: The aim of this study is to assess the prevalence of oral mucosal lesions in periurban area in the city of Lucknow aged 15 years and above. Settings and Design: A multistage random sampling was done for identifying the study sample. Materials & Methods: In the first stage. all peri-urban areas of Lucknow city was grouped into four geographical zones. Second stage consisted of random selection of 20 peri-urban areas by lottery method (5 from each zone). In third stage there was selection of individuals using simple random method. A total of 45 individuals was selected. Thus a total 900 individuals was selected (i.e. 225 from each zone). Results: The prevalence of oral mucosal lesion in the present study was found to be 11.8%. The percentage of patients suffering from leukoplakia, oral submucous fibrosis and lichen planus was 51.9%, 20.8% & 11.3% respectively. Conclusion: This survey high-lighted the rampant misuse of variety of harmful substances as well as the high prevalence of oral lesions in the community.
