乳头状涎腺腺瘤是一种罕见的外生性、良性涎腺肿瘤。乳头状涎腺腺瘤的名称,是Abrams和Finck 1969年提出的,它表现为导管上皮的乳头状和外生性增殖,并伴有表面鳞状上皮的增生,被认为是一种独立病变。其组织形态学表现类似皮肤乳头状汗腺腺瘤。自Abrams和Finck报道之后,又有一些报道,但对其生物学性质和来源尚有待证实。本文作者报告一例年龄为56岁、男性、日本人的硬腭部病变的超微结构,并讨论了其组织发生。标本以10%缓冲福尔马林固定,磷酸缓冲液(pH7.3)清洗过夜后,按常规电
Papillary parotid adenoma is a rare exogenous, benign parotid gland tumor. The name of papillary salivary adenomas, proposed by Abrams and Finck in 1969, is the appearance of papillary and exogenous proliferation of ductal epithelium with hyperplasia of surface squamous epithelium and is considered as an independent lesion. Its histological appearance resembles that of papillary sweat gland adenomas. After reports by Abrams and Finck, there have been some reports, but their biological properties and sources have yet to be confirmed. The authors report the case of a 56-year-old, male, and Japanese patient with an ultrastructure of hard palate lesions and discuss their histogenesis. Specimens were fixed with 10% buffered formalin and washed overnight with phosphate buffer (pH 7.3).
