Sialoblastoma: A very rare cervical mass in neonates: A case report

Sialoblastomas are very rare epithelial tumors of the salivary gland that usually occur in the parotid or submandibular gland. Most sialoblastomas present in the neonatal period or early childhood. The biological behavior of these tumors is variable, with a potential for local and systemic recurrences. Only ten cases in the submandibular gland have been reported so far. We are reporting a case of sialoblastoma in a newborn male child presenting in the right submandibular region. Ultrasound visualized a homogeneous solid mass. MRI showed a well-defined soft tissue solid mass in right submandibular region. Alpha fetoprotein was 18.8 ng/ml (normal 0.4-15). Fine needle aspiration showed cylindrical connective tissue with groups of basilar cells. Mitosis was not seen. The most probable diagnosis was sialoblastoma.
