小涎腺的囊性病变临床上很常见,粘液腺囊肿实际上可分为外渗型和潴留型。当粘液渗入结缔组织并被肉芽组织包绕时称为粘液外渗性囊肿;而潴留性囊肿是指含有潴留的粘液,并由导管上皮衬里的囊肿。这种导管上皮可能发生鳞状化生或瘤细胞化生(onc-ocytic,metaplasia)。粘液囊肿常常是单发的,但有时存在多个,手术切除不当常出现复发。Gorlin 和Goldman 曾报告1例下唇多发性粘液外渗性 Small salivary cystic lesions are clinically very common, mucinous gland cysts can actually be divided into extravasation type and retention type. A mucus extravasation cyst is known as mucus infiltrates connective tissue and is surrounded by granulation tissue. A retention cyst refers to a cyst that contains mucus that is retained by the lining of the ductal epithelium. This ductal epithelium may undergo squamous metaplasia or onc-ocytic metaplasia. Mucous cysts are often single, but sometimes there are multiple, improper surgical resection often recurrence. Gorlin and Goldman have reported a case of multiple mucus extravasation of the lower lip
