<unk>  is most likely to occur in adults around 50 years of age. There is a predilection for gender with 60–80% being female. The gland affected has a diffuse swelling. The swelling can be asymptomatic, but mild pain can also be associated. There is a preponderance of this disease in those who suffer from HIV infection. Most cases of<unk> s appear in conjunction with Sjögren's syndrome. When Sjögren's syndrome is present, the swelling is usually bilateral. Otherwise, the affected glands are usually only on one side of the body. In many cases, a biopsy is needed to distinguish<unk> s from sialadenosis (sialosis).
