Lipoma is a benign mesenchymal tumor of fat with uncertain pathogenesis. Although the most common mesenchymal neoplasm in trunk and proximal portions of the extremities, it is rarely seen in the oral cavity. Oral lipomas are clinically soft, smooth-surfaced nodular masses that mostly are less than 3 cm in size. Typically the tumor is asymptomatic unless bitten or become noticeable because of their size. The buccal mucosa and buccal vestibule are the most common intraoral sites and account for 50% of all cases. Reported here is a relatively large lipoma of buccal mucosa that was treated surgically under local anesthesia. In an 18-month postsurgical follow up no complication or recurrence has occurred. This case will also be compared to intraoral lipomas reported in Iranian population. As lipomas are usually smaller than 3 cm in diameter, lipoma with the size reported, is of clinical importance. Since the large lipomas are in differential diagnosis with other, even malignant, mesenchymal, or salivary gland tumors. Thus, this case report recommends clinical awareness in diagnosis of large intraoral soft tissue lesions.
脂肪瘤是一种发病机制不明的良性脂肪间叶组织肿瘤。尽管它是躯干和四肢近端最常见的间叶组织肿瘤，但在口腔中却很少见。口腔脂肪瘤临床上表现为质地柔软、表面光滑的结节状肿物，大小多小于3cm。通常情况下，除非被咬伤或因其大小变得明显，肿瘤一般无症状。颊黏膜和颊前庭是口腔内最常见的部位，占所有病例的50%。本文报道了一例在局部麻醉下接受手术治疗的相对较大的颊黏膜脂肪瘤。术后18个月的随访中未出现并发症或复发。该病例还将与伊朗人群中报道的口腔脂肪瘤进行比较。由于脂肪瘤直径通常小于3cm，本文报道的这种大小的脂肪瘤具有临床意义。因为较大的脂肪瘤需要与其他甚至恶性的间叶组织或唾液腺肿瘤进行鉴别诊断。因此，本病例报告建议在诊断口腔内较大软组织病变时提高临床意识。
