Submandibular gland pleomorphic adenoma in a seven-year-old child: a case report.

Salivary gland neoplasms are rare in the pediatric age group. Pleomorphic adenomas in the submandibular gland are rarer. In this article, we present a seven-year-old female with a slowly growing mass in her right submandibular area. The firm, mobile and painless mass was about 2x3 cm in size and with bimanual palpation it was indiscriminated from the submandibular gland. Magnetic resonance imaging with contrast revealed a heterogeneous and minimally lobulated mass within the submandibular gland with clearly defined borders. Fine needle aspiration biopsy revealed a diagnosis of pleomorphic adenoma and we performed right submandibular gland excision under general anesthesia. The histopathological diagnosis was pleomorphic adenoma with sparse mitotic figures that may be interpreted as having a potential of malignant transformation. This patient who was followed up for one year without any complication is to our knowledge the youngest case cited in the English-language literature.
