Lipoma of mandibular buccal vestibule: a case with histopathological literature review

Abstract

Lipoma is a tumour of soft tissue with rare occurrence in oral cavity accounting for only 1-4% of benign oral tumours. Most common sites of involvement are the buccal mucosa, tongue and floor of the mouth with typical presentation of an asymptomatic, soft, smooth-surfaced, nodular and yellowish mass. Histopathologically, a classical lipoma resembles normal adipose tissue and it has multiple variants which are less commonly seen except fibrolipoma. The article presents a case report of a relatively large oral classical lipoma in a 60-year-old man on a rare site, mandibular buccal vestibule, along with a review of the literature and special emphasis on its various histopathological variants.

Oral lipoma: Case report and review of literature

“…Oral lipoma, a benign tumor of mesenchymal origin, is composed of mature adipocytes and is usually separated by a thin fibrous connective tissue capsule . Roux was the first to describe soft tissue lipoma in 1848 as a yellowish epulis, and Cornil and Ranvier presented the first case of intraosseous lipoma (IOL) in 1880 .…”

“…Most cases of oral lipoma are soft tissue lesions. About 15%‐20% of soft tissue lipomas occur in the head and neck area, of which only 1%‐4% are observed intraorally . The incidence of IOL is very low, about 0.1% and infrequently seen in the maxillofacial region .…”

“…The incidence of IOL is very low, about 0.1% and infrequently seen in the maxillofacial region . Oringer reported the first case of mandibular IOL in 1948 …”

Prevalence of oral lipomas in Indian population: An institutional retrospective study of 12 years and analysis of 49 published cases from 1976 – 2017 reported in Indian patients

“…(Table 3). (1,3,7,14,15,16,21,47,48) Clinically most of the lipomas presented as a soft tissue painless growth, irrespective of their histological diagnosis and they often masquerade other common neoplastic and reactive growths of oral cavity i.e. peripheral giant cell granuloma, fibroma, pyogenic granuloma etc.…”

Oral lipoma located at the left lower vestibule-report of a case and a brief review of the literature

“…The oral lipoma is a benign neoplasm, probably of mesenchymal origin, composed of the mature adipocytes, usually covered by a fibrous capsule 1,2 . Roux was the first who described this oral lesion in 1848. when he referred lipoma as yellowish epulis 3 .…”
