Congenital Pleomorphic Adenoma in a SubmandibularGland of a Newborn- A Case Report.
BACKGROUND
Pleomorphic adenoma is a rare benign salivary gland neoplasm in children, which can be treated by simple excision. This tumor is rarely included in the differential diagnosis of solid submandibular masses in children. In the neonates, congenital pleomorphic adenoma usually presents in the nasopharynx. Surgical excision is the treatment of choice and recurrence is not expected. We report what appears to be the first case of congenital pleomorphic adenoma in the submandibular region in a one-day-old newborn.


METHODS
The case of a one-day-old term baby is presented with a 5x2 cm left submandibualr mass with extension to the oral cavity. The mass was hard and non-mobile. During Ultrasonography and Contrast-enhanced Computed Tomography (CT) scan, the mass was solid with a heterogeneous internal structure. The tumor was completely excised and proved to be a pleomorphic adenoma during histopathological examination.


CONCLUSIONS
Congenital pleomorphic adenoma rarely occurs in the nasopharynx and is treated by surgical excision. Our case is unique because the congenital pleomorphic adenoma is located in the submandibular gland of a newborn.
