Abstract:
Sialolipoma is a rare tumor found within both major and minor saliva. Benign fatty tumors of parotid gland (lipomas) are very unusual, accounting for less than 0.5% of all parotid tumors. Sialolipoma, a distinct variant, is characterized by proliferation of mature adipocytes with secondary entrapment of normal salivary gland elements. Sialolipoma is well circumscribed and contains mature adipose tissue admixed with benign salivary gland component. We report a case of 51 years old female who presented with the complaint of swelling in the right parotid region for 12 years duration. Ultrasonography suggested adenoma and FNAC suggested a cystic lesion. Histopathological examination after superficial parotidectomy reported sialolipoma. The aim of this article is to report a case of sialolipoma, discuss the features and contribute to differential diagnosis. There are very few reported cases of sialolipoma in the existing English literature.
摘要:
唾液酸脂瘤是在主要和次要唾液中发现的罕见肿瘤。腮腺良性脂肪瘤(脂肪瘤)非常罕见,占所有腮腺肿瘤的0.5%以下。Sialolipoma,一个独特的变体,其特征是成熟脂肪细胞的增殖和正常唾液腺元素的二次截留。唾液酸酶瘤界限清楚,含有成熟的脂肪组织,与良性唾液腺成分混合。我们报告了一例51岁的女性,其主诉为右腮腺区域肿胀,持续了12年。超声检查提示腺瘤,FNAC提示囊性病变。浅表腮腺切除术后的组织病理学检查报告唾液酸脂瘤。本文的目的是报告一例唾液酸脂瘤,讨论的特点,并有助于鉴别诊断。在现有的英语文献中,很少有报道的唾液酸脂瘤病例。
