Chronic sclerosing sialadenitis is a chronic inflammatory salivary gland disease. Küttner
reported 4 cases of submandibular gland lesions for the first time in 1896. Chronic sclerosing
sialadenitis is a very rare inflammatory lesion of the parotid gland and cannot be easily distinguished
from salivary malignant masses. We reported a 28-year-old male with a painful parotid tumour,
which grew slowly for 4 years.
