“…CT is reportedly the most useful modality for imaging diagnosis. As the CT attenuation value of adipose tissue is characteristically around -100 HU, lipoma shows similar values [21]. In this patient, the attenuation value was -90 HU, which was useful for reaching a diagnosis.…”

Lipoma is relatively uncommon in the oral cavity. Among the intraoral regions, lipoma involving the gingiva or gingivobuccal fold is relatively infrequent. We report the case of a patient with lipoma extending superiorly from the mandibular gingivobuccal fold to the gingiva. In addition to the case report, we retrospectively reviewed 207 patients with intraoral lipoma reported in Japan from 1987 to 2004. The most frequent site of development was the buccal mucosa (40.6%), followed by the tongue (17.9%), lip (12.6%), gingiva (8.7%), oral floor (6.8%), gingivobuccal fold and palate (4.8%), and others (3.9%). Occurrence tended to be more frequent in males (57.5%) than in females (42.5%). Relative to age, frequency peaked among patients in the 7th (27.3%) and 6th decades (25.1%), respectively, followed in descending order by the 5th (14.8%) and 8th decades (13.1%). The majority of patients (86.3%) were at least 40 years. The most frequent size was 10-19 mm (37.5%), followed by 0-9 mm (27.8%) and 20-29 mm (14.6%), and tumors 30 mm or larger were relatively infrequent. Histopathological types in order of descending frequency were lipomas (69.0%), fibrolipomas (27.4%), and others (3.5%). The male:female ratio was 1.7:1 for lipoma and 1:1.6 for fibrolipoma.

“…Sonographically, they are moderately compressible. Compared with the parotid parenchyma, pure fat-containing lipomas are moderately hypoechogenic lesions [38,39,40]. Typically, a striated, feathered echogenicity is found at sonography (Fig.…”

“…Lipomas are mesenchymal tumors found most frequently in soft tissue, but also occurring rarely in the mouth 2 Microscopically, it is not possible to distinguish normal adipose tissue from lipomas; however, metabolic differences are found due to the fact that lipomas are not used as a form of energy, as happens with normal adipose tissues. This fact is related to the activity of the lipoprotein lipase which is notably greater in lipomas 5,6,9 . Lipomas may be classified as classic and variants, according to the amount and type of tissue found.…”

“…Occurrence of lipoma in the oral and maxillofacial cavity is rare [4][5][6] ; the frequency reported in the literature on oral lipoma (OL) is between approximately 1 5 to 5% 6 . These tumors can attack the tongue, lips, gingiva, floor of the mouth, salivary glands and oral mucosa [1][2][3][4][5][6] .…”

ResumoIntrodução: Os lipomas consistem em tumores benignos com origem mesenquimal que podem ser observados nos locais onde, normalmente, têm-se a presença de tecido adiposo. A localização mais comum para estas lesões consiste no tronco e na porção terminal das extremidades, sendo, porém, possível a ocorrência destas lesões na cavidade oral. Objetivo: O presente trabalho visa realizar uma breve revisão de literatura sobre os LO, bem como relatar um casos clínico. Material e método: No presente trabalho foi realizado o tratamento cirúrgico de um paciente com aumento de volume em região de mucosa jugal. Resultado e conclusão: O presente trabalho apresenta um caso clínico de um lipoma bem como o tratamento satisfatório do caso sem recidiva da lesão.Descritores: Cirurgia oral; lipoma; patologia bucal. AbstractIntroduction: Lipomas consist of benign tumors of mesenchymal origin that may be found in locations where adipose tissue is normally present. The most common locations for these tumors are the trunk and the end-points of the extremities. However, these tumors may occur in the oral cavity. Objective: The present study conducts a brief review of the literature on oral lipoma (OL) and reports a clinical case. Material and Method: Surgical treatment of a patient with swelling in the region of the jugal mucosa was performed for the present study. Result and conclusion: The present study presents a clinical case of a lipoma, as well as the satisfactory treatment of the case with no recurrence of the tumor.
