Abstract
Background:Lipomas are benign mesenchymal tumors of soft tissue that can be found anywhere in the body: However their presence in oral cavity is very rare (4.4%). Histopathologically lipomas are classified as simple lipomas and different variants. The present study describes the prevalence of oral lipomas with relation to patient’s age, their site of occurrence and histological pattern in Indian population.Methods:All cases of oral lipomas reported in the department of oral pathology and microbiology, N.I.M.S dental college Jaipur (India) from 2005 to 2017 for age, gender, site of occurrence, histopathological pattern and treatment mode were reviewed. The published case reports of oral lipomas reported in Indian patients from 1976 – 2017 also reviewed through pubmed by using MeSH word; oral lipoma and combined the data with the data of present study to analyze the prevalence and histopathological characteristic of oral lipomas in Indian population.Results:Total of 23 (14 males and 9 females) cases included in the study. The mean age was 34.3 years (range 17 – 71). The specific sites involved were buccal mucosa (n = 9) Tongue (n = 5) buccal vestibule (n = 2) Lip (n -= 3) Floor of mouth (n = 1), palate (n = 2) and retro molar pad (n = 1). Histopathological examination revealed 11 cases were diagnosed as simple lipoma, 6 cases were fibrolipoma, 2 cases were angiolipoma, 1 case each of osteolipoma, myxolioma, angiomyxolipoma and hibernoma. All cases treated with surgical excision only one case showed radiographical sign. This data was combined with the data of published cases (pubmed) of oral lipoma in Indian population.Conclusion:Oral lipomas are rare neoplasms of oral cavity; only 49 published cases have been found from 1976 – 2017 in Indian population. Oral lipoma should be considered as a differential diagnosis of oral soft tissue swelling. Surgical excision is the treatment of choice for all such tumors.
Highlights
Lipomas are commonest tumors in humans; while their occurrence in oral cavity is exceedingly rare (4.4 % of all benign oral soft tissue tumors). [1] Their aetiology and pathogenesis remain unclear, mechanical, endocrine and inflammatory influences have been reported. [2] Lipomas are usually soft, well circumscribed, painless and slow growing tumors
In addition we reviewed all published cases from 1976 to 2017 reported in Indian patients found in pubmed by using MEsH word oral lipoma
We combined the results of our cases with the published cases to find out the prevalence of oral lipomas in Indian population pertaining to histopathological paatern, tumor site, age, gender and treatment modality
Summary
Lipomas are commonest tumors in humans; while their occurrence in oral cavity is exceedingly rare (4.4 % of all benign oral soft tissue tumors). [1] Their aetiology and pathogenesis remain unclear, mechanical, endocrine and inflammatory influences have been reported. [2] Lipomas are usually soft, well circumscribed, painless and slow growing tumors. The present study was aimed to describe the clinical and histological behaviour of oral lipomas in an Indian population. The present study describes the prevalence of oral lipomas with relation to patient’s age, their site of occurrence and histological pattern in Indian population. Methods: All cases of oral lipomas reported in the department of oral pathology and microbiology, N.I.M.S dental college Jaipur (India) from 2005 to 2017 for age, gender, site of occurrence, histopathological pattern and treatment mode were reviewed. All cases treated with surgical excision only one case showed radiographical sign This data was combined with the data of published cases (pubmed) of oral lipoma in Indian population. Conclusion: Oral lipomas are rare neoplasms of oral cavity; only 49 published cases have been found from 1976 – 2017 in Indian population.
