Sialoblastoma. diagnosis by FNAC: A case report

Abstract

Tumors of salivary gland are very uncommon in children and comprise of <5% of all salivary gland tumors. Most of these neoplasms originate in the parotid gland with 10-15% arising from the submandibular, sublingual, and minor salivary glands. We report a case of sialoblastoma in an 8-year-old male child who presented with a history of slowly progressive swelling of the parotid gland since birth, which was soft to firm in consistency and mobile in all directions. Magnetic resonance imaging showed a well encapsulated tumor located in the superficial lobe of the left parotid gland. Fine needle aspiration was performed, which revealed a parotid tumor with closest resemblance to sialoblastoma. Superficial parotidectomy was performed. The histopathology confirmed the diagnosis of sialoblastoma. Sialoblastoma should always be considered when the lesion is known or suspected to be congenital.
