成熟脂肪细胞的良性软组织肿瘤称为脂肪瘤(脂肪细胞)。脂肪瘤可以在身体的任何地方发展,虽然它在嘴里并不常见。表面定位的脂肪瘤通常呈黄色,无痛,软,并且不波动,上皮表面薄。因此,表面上经常看到微妙的血管图案。更深的病变可能不会表现出这一发现,因此,不是临床公认的。由于患者没有报告任何主观临床症状,牙医经常偶然诊断出这种脂肪瘤。深部脂肪瘤需要专门的影像学检查,比如对比增强计算机断层扫描,磁共振成像,或超声波来确定它们的范围。脂肪瘤的大小范围可以从微小到大到巨大。大型脂肪瘤通常具有“滑脱征”和结节状表面。巨大脂肪瘤的直径可达10厘米。脂肪瘤可以是单细胞或多细胞的。皮肤病,变形杆菌综合征,神经纤维瘤病,家族性腺瘤性息肉病在不同部位均表现为脂肪瘤。这些口腔脂肪瘤的优选治疗过程是手术切除。此类脂肪瘤不会再复发。脂肪瘤有许多微小的品种。传统的描述是由均匀大小和形状的成熟脂肪细胞的小叶组成的明确定义的肿瘤。术语“纤维脂肪瘤”是指含有大量纤维结缔组织的脂肪瘤,“血管脂肪瘤”是指含有许多微小血管的脂肪瘤,“粘液瘤”是指具有粘液样细胞背景的脂肪瘤,和“梭形细胞脂肪瘤”是指含有均匀梭形细胞混合物的脂肪瘤。与多形性脂肪肉瘤相比,多形性脂肪瘤表现出梭形细胞和奇怪的,超色大细胞,这让病理学家很难区分它们。肌内脂肪瘤是侵入骨骼肌束的脂肪瘤。因为它们很难完全根除,肌内脂肪瘤更容易复发。
A benign soft tissue tumor of mature fat cells is called a lipoma (adipocytes). Lipoma can develop anywhere on the body, although it is uncommon in the mouth. Lipomas that are superficially positioned are often yellowish in color, painless, soft, and non-fluctuating with a thin epithelial surface. As a result, a delicate pattern of blood vessels is frequently seen on the surface. Deeper lesions might not exhibit this finding and, as a result, are not as clinically recognized. Since the patients do not report any subjective clinical symptoms, the dentist often diagnoses such lipomas by accident. Deep-seated lipomas require specialist imaging procedures, such as contrast-enhanced computed tomography, magnetic resonance imaging, or ultrasound to determine their extent.
Lipomas can range in size from tiny to large to enormous. Large
lipomas typically feature a \"slip sign\" and a nodular surface. Giant-sized
lipomas can have a diameter of up to 10 cm.
Lipomas can be single or multicellular. Dercum\'s disease, Proteus syndrome, neurofibromatosis, and familial adenomatosis polyposis all exhibit lipomas in various locations. The preferred course of treatment for these oral lipomas is surgical removal. Such
lipomas do not recur again. Lipoma comes in a number of tiny varieties. The traditional description is of a well-defined tumor made up of lobules of uniformly sized and shaped mature fat cells. The term \"fibrolipoma\" refers to lipomas that contain a sizable amount of fibrous connective tissue, \"angiolipoma\" refers to lipomas that contain numerous tiny blood vessels, \"myxolipoma\" refers to
lipomas with a background of myxoid cells, and \"spindle cell lipoma\" refers to
lipomas that contain a mixture of uniform spindle cells. When compared to a pleomorphic liposarcoma, the pleomorphic lipoma exhibits spindle cells and strange, hyperchromatic large cells, making it challenging for the pathologist to tell them apart. An intramuscular lipoma is a lipoma that invades skeletal muscle bundles. Because they are harder to entirely eradicate, intramuscular lipomas are more likely to reoccur.
