Sialometaplasia arising in the ectopic salivary gland ductal inclusions of multiple intraparotid lymph nodes

J Clin Pathol. 2004 Dec;57(12):1335-7. doi: 10.1136/jcp.2004.017202.

Abstract

Sialometaplasia, squamous metaplasia of salivary gland lobules, is a benign condition occasionally presenting with lesions clinically simulating malignancy. "Necrotising sialometaplasia", recognised by lobular infarction, necrosis, and simultaneous squamous metaplasia of ducts and acini is a well known condition. There are only a few reports of the "proliferative type of sialometaplasia", which is recognised by a more mature morphology of larger and more irregular metaplastic nests, lacking necrosis. This report describes a unique case of "proliferative sialometaplasia of multiple intraparotid lymph nodes" occurring in a 55 year old woman, presenting with multiple parotid lumps. This interesting case points to the importance of intraparotid lymph nodes as sites for multiple lesions of the parotid region.
