Abstract

An extremely rare case of fibrolipoma in the hard palate is presented and discussed with reference to the literature. An 85-year-old woman visited the Tokyo Dental College Chiba hospital in September 2016 with the chief complaint of a mass in the hard palate. The patient had first become aware of this mass several years earlier. An examination at another hospital in June 2009 resulted in a clinical diagnosis of lipoma. Regular examinations followed every 6 months until September 2014, at which time she stopped attending these appointments because there was no change. In August 2016, however, the patient realized that the tumor was increasing in size. Although there was no pain, awareness of a foreign body in the oral cavity when eating or talking was increasing, so she decided to visit our clinic for detailed examination and treatment. At this point, the mass extended from the center to the left side of the hard palate. It measured 15 mm along the major axis, and had a clear border; nearly spherical, its surface was smooth and glossy, and was of a slightly yellowish color. The mass was painless, elastic, and soft. Computed tomography and magnetic resonance imaging revealed a tumorous lesion. Based on a clinical diagnosis of lipoma, it was subsequently excised under general anesthesia in January 2017. The tumor lay under the palatal mucosa, extending from the center to the left side of the hard palate. It was surrounded by a single-layered membranous structure, and had not adhered to the surrounding tissues. Healthy palatal mucosa and periosteum were also removed en bloc with the tumor within a safety margin of approximately 5 mm. No pressure absorption of palatine bone was seen. Histopathologically, proliferation of mature adipose tissue was observed. This was surrounded by a thin, single-layer membrane within the subepithelial connective tissue, which was covered by stratified squamous epithelium. Proliferation of fibrotic connective tissue was seen between the adipocytes. The final diagnosis was fibrolipoma. To date, at 18 months postoperatively, no recurrence has been observed and progress has been satisfactory.

硬腭纤维脂肪瘤1例。
本文报告一极为罕见的硬腭纤维脂肪瘤病例,并参考文献进行讨论。2016年9月,一名85岁的女性前往东京牙科学院千叶医院就诊,主诉是硬腭肿块。病人在几年前首次意识到这个肿块。2009年6月在另一家医院进行检查,临床诊断为脂肪瘤。每6个月定期检查一次,直到2014年9月,因为没有变化,她停止了这些预约。然而,在2016年8月,患者意识到肿瘤的大小越来越大。虽然没有疼痛,但进食或说话时对口腔异物的意识越来越强,所以她决定来我们诊所进行详细的检查和治疗。此时,肿块从硬腭中央延伸到左侧。它沿长轴长15毫米,边界清晰;它几乎是球形的,表面光滑而有光泽,颜色略带黄色。肿块无痛,有弹性,柔软。计算机断层扫描和磁共振成像显示肿瘤病变。基于脂肪瘤的临床诊断,随后于2017年1月在全身麻醉下切除。肿瘤位于腭黏膜下,由硬腭中央向左侧延伸。被单层膜状结构包围,未与周围组织粘连。健康的腭黏膜和骨膜也在大约5毫米的安全范围内与肿瘤一起切除。腭骨未见压力吸收。组织病理学观察成熟脂肪组织增生。它被上皮下结缔组织内的薄单层膜所包围,并被层状鳞状上皮所覆盖。脂肪细胞间可见纤维化结缔组织增生。最终诊断为纤维脂肪瘤。到目前为止,在术后18个月,没有观察到复发,进展令人满意。
