Canalicular adenoma is a uncommon benign salivary gland tumor and it most frequently involves minor salivary gland of upper lip. It rarely occurs in parotid gland. The canalicular tumor of parotid gland can be manifestes clinically and pathologically as a multifocal lesion, which is not generally seen with other intraoral salivary gland tumors. Recently, we experienced a case of multifocal canalicular adenoma occurred on parotid gland in a 65-year-old woman and report it to support the view that canalicular adenoma occur rarely in parotid gland, and is recognizable entities.

Parotid canalicular adenoma is a benign neoplasm that is predominantly composed of branching and interconnecting cords of single or double rows of columnar epithelium in a very loose stroma. There has been considerable confusion in the literature concerning the terminology of canalicular adenoma. However, thesedays it has been newly-recognized as a discrete entity of the monomorphic adenoma group. Canalicular adenoma has a remarkable predilection for occurrence in the minor salivary glands such as the upper lip, in contrast with basal cell adenoma that occurs predominantly in major salivary glands such as the parotid gland. We have experienced a case of canalicular adenoma of the parotid gland in a 65-year-old woman. The patient had a palpable mass on the preauricular area for the last 15 years and recently noticed a mild pain and discomfort on the mass. Neck ultrasonography showed a low echogenic mass of 1.0cm in diameter in the right parotid gland and a neck CT scan showed a well-enhanced rectangular-shaped mass. A superficial parotidectomy was performed for the lesion and the final pathologic diagnosis turned out to be 'multifocal canalicular adenoma'.
