T/NK-cell lymphoma of the salivary gland is rare. A 58-year-old man complained of a tumor mass in the left parotid gland region and he was diagnosed to have a left parotid tumor. The tumor was subsequently resected, revealing a diffuse growth pattern of medium to large sized atypical cells. The tumor was surrounded by fibrous connective tissue in the form of a capsule, and those were positive for CD3, CD4, CD5 and CD30, but negative for Bcl2, CD8, CD10, CD15, CD20, CD25, CD56, CD79a, CD246, EMA, granzyme B, TdT and TIA-1. There was no molecular evidence of Epstein-Barr virus (EBV) infection. It was diagnosed as peripheral T-cell lymphoma (PTCL) arising from an intraglandular lymph node in the parotid gland. In conclusion, Only 17 cases of primary T/NK-cell lymphoma of the salivary glands have been recorded until now, and the characteristics of these are not clear yet. Additional study is needed.
