Abstract
Lipomas are benign tumours of mesenchymal origin (mature adipocytes) that are comparatively uncommon in the oral cavity corresponding to less than 4.4% of all benign oral soft tissue tumors. Clinically, they present as slow growing, soft, asymptomatic masses. Histopathologically, they appear as thinly encapsulated lesion composed of mature adipocytes with inconspicuous vascularity. The pathogenetic mechanisms of oral lipomas are still unclear. They are usually treated by surgical excision and bear excellent prognosis. Here we report a case of intraoral lipoma in 54 year old male patient in the left lower lingual alveolar mucosal region that was treated by surgical excision using electrocautery without any postsurgical complication. One-year follow-up showed no evidence of recurrence.

Summary
Lipomas are the most common benign mesenchymal tumors surrounded by a thin fibrous capsule.[1]. The most common intraoral site for lipoma is buccal mucosa and buccal vestibule. Lipoma commonly occur in the 5th or 6th decades of life and are usually asymptomatic until they grow to large size and may interfere with speaking and mastication.[2] The diagnosis is mainly based on clinical findings with histopathology to rule out other lesions in the same site. Solitary, soft, sessile, lobulated mass is seen in the left lingual gingival region extending to alveolar mucosa round in shape, 1.8x1.3 cm in size located in relation to 33, 34 and 35. Histopathological examination (Figure 5) revealed normal appearing parakeratinized stratified squamous epithelium. The underlying connective tissue reveals numerous benign looking mature adipocytes in the deeper areas with extravasations of RBC at places .A final diagnosis of lipoma was made. The patient is currently being monitored and so far no recurrence has occurred (Figure 4)
