Asymptomatic nodules of the upper lip: report of a canalicular adenoma with immunoprofile presentation.

Canalicular adenoma is an uncommon benign tumour that generally arises in the minor salivary glands of individuals over 60 years old. This study illustrates a case of canalicular adenoma in a 70-year-old female, presenting as two distinct asymptomatic nodules in the upper lip. Immunohistochemistry analysis was performed. Clinical features, management, histology and immunoprofile from this case and from the literature are discussed.
