Abstract
Sialadenosis is defined as a non-inflammatory, non-neoplastic enlargement of the salivary glands. This disease is widely recognized to usually affect the parotid glands as recurrent bilateral swelling and is also accompanied by either endocrine or metabolic disorders in a large number of such cases. In contrast to the majority of reports on sialadenosis, we experienced one non-typical case of sialadenosis. This patient presented with a solid, tumor-like mass in the unilateral parotid gland without any general disorders. We initially considered this to be a benign parotid tumor until a histological diagnosis was performed after the tumor was resected.
