Abstract

The first patient was a 56-year-old female with a solitary mass of the right parotid gland. The second patient was a 74-year-old female with a solitary mass of the right parotid gland. The third patient was a 60-year-old male with a solitary mass of the left parotid gland. Sjögren's syndrome was present only in the first patient. CT scans and echograms demonstrated a well-circumscribed mass in all three, and we treated and removed these lesions as a parotid tumor. The pathological findings in all three resected tumors were atrophy of the glandular parenchyma and diffuse lymphocytic cell infiltration. The pathological findings of the lesion with strong histological change were islands of epithelial cells (epimyoepithelial islands), but no neoplastic changes were found. It was reported recently that benign lymphoepithelial lesion (BLEL) can change to a neoplastic tumor. Therefore, it is necessary to follow BLEL patients for a long time.
