Abstract
Background
Xanthogranulomatous tissue reaction is a well-documented process that is most common in kidney. There are other uncommon sites being documented as case reports in the literature. We would like to describe the clinicopathologic findings in a case of xanthogranulomatous sialadenitis that involved the parotid gland, which was clinically thought to be a tumoral mass, and compare it with the 4 previously reported cases.
Case report
A 52-year-old man presented with a left parotid mass. Fine needle aspiration biopsy was consistent with Warthin's tumor. The mass lesion was excised.
Discussion
The lesion measured 2.5 × 1.5 × 1.5 cm. Microscopic examination revealed sheets of foamy macrophages centrally admixed with neutrophils, eosinophils, lymphocytes, plasma cells and scattered giant cells indicating a xanthogranulomatous reaction.
As a conclusion xanthogranulomatous tissue reaction can mimic neoplasms.
