“…Oral lipomas and their histological variants are observed across all age groups but are predominantly seen in individuals between 40 and 60 years of age, with a higher prevalence among women for fibrolipomas. [ 2 ] An analysis involving 1 patient from our hospital and a review of 671 cases cited in this study revealed that the age of onset ranged from as young as 4 months to as old as 92 years, with a peak incidence between 40 and 60 years. This pattern aligns with findings reported in both domestic and international research.…”

“…Nevertheless, a 14-year retrospective study analyzing the clinical and morphological characteristics of oral lipomas identified the buccal mucosa as the most frequently affected area, followed by the tongue, with the lower lip being an uncommon site. [2] The histopathological spectrum of oral and maxillofacial lipomas includes traditional lipomas, fibrolipomas, spindle cell lipomas, salivary lipomas, osteolipomas, chondrolipomas, and intramuscular lipomas. Fibrolipoma, distinguished by a dense network of fibrous collagen and mature fat cells, is classified by the World Health Organization as a rare histological subtype of traditional lipomas.…”

Background: Fibrolipoma of the lower lip is an uncommon condition with limited documentation in the literature. This paper provides updated insights into oral and maxillofacial lipomas through a detailed case report and comprehensive literature review, discussing clinical features, pathogenesis, diagnostic approaches, histopathology, and therapeutic strategies. Case presentation: A 54-year-old female presented with a painless, enlarging mass on the inner aspect of her right lower lip, first noticed 2 years prior. The mass, now the size of a peanut, interfered with her eating and speech. Physical examination revealed a 2.0 × 2.5 × 1.0 cm mass beneath the mucous membrane of the right lower lip. It was firm, well-demarcated, and mobile. Surgical excision was performed, and histopathological analysis confirmed the diagnosis of a lower lip fibrolipoma. The lesion was successfully removed without recurrence. Conclusion: Lipomas in the oral and maxillofacial regions are rare, slow-growing benign tumors, particularly within the lips. Although their diagnosis is straightforward based on clinical presentation, histopathological confirmation is essential. Surgical resection remains the treatment of choice, with excellent prognostic outcomes.

“…The histopathological findings of lipomas arising within the soft tissue are predominantly an array of mature adipocytes divided into lobules by connective tissue septa. A thin fibrous capsule usually surrounds the tumor 25 . Although lipomas occurring in the oral cavity are rare, the diagnosis is based on clinical findings of round, submucosal soft nodules that are yellowish in color 26 .…”

BackgroundMass lesions occurring under the oral mucosal epithelium are often small and difficult to diagnose; however, intraoral ultrasonography can delineate these lesions. We aimed to investigate the features of submucosal mass lesions in the oral cavity using intraoral ultrasonography.MethodsFifty patients with hemangioma, irritation fibroma, mucous cyst, lipoma, and pleomorphic adenoma were included. Age, site, largest diameter, thickness, marginal morphology type, border type, internal echo posterior echo, and internal or peripheral Doppler images of the lesions were recorded.ResultsThe hemangiomas were internally hypoechoic and exhibited a cord‐like structure; irritation fibromas, mainly internally isoechoic; mucous cysts, hypoechoic; and the lipomas appeared as homogeneous, isoechoic, or hyperechoic images with unclear borders. Pleomorphic adenomas were surrounded by a single hypoechoic zone, suggesting a thick capsular structure, were predominantly isoechoic internally, and appeared as cyst‐like hypoechoic images.ConclusionsThe features of the lesions were identified and delineated using intraoral ultrasonography.
