Parotid Neoplasms in Pediatric Population: A Single Institute Experience

Abstract

Background: salivary gland neoplasms are rare in pediatric age group with pediatric parotid neoplasms account for most of them, mucoepidermoid carcinoma is the most common malignant variant while pleomorphic adenoma is considered the most common benign variant among them.

Methods: this is a retrospective cohort study that included 41 pediatric patients with parotid lesions the aim is to present our institutional experience with the evaluation of pathological features and management of pediatric parotid gland tumors.

Results: the median age was 12 years old. (26.8%) were female and (73.2%) were male, radiological investigations were CT & MRI in (17.1%), ultrasound alone in (12.2%), ultrasound & CT in (68.3%), ultrasound & MRI (2.4%); pathological investigations were FNAC alone in (80.5%), FNAC and true cut biopsy in (19.5%) cases. pathological results; adenoid cystic carcinoma (7.3%), cavernous hemangioma in (2.4%), Hodgkin lymphoma in (12.2%), mucoepidermoid carcinoma in (29.3%), myoepithelioma in (2.4%), pleomorphic adenoma in (34.1%), rhabdomyosarcoma (anaplastic variant) in (2.4%) and rhabdomyosarcoma (embryonal variant) in (7.3%) cases.

Conclusion: 58.5% of pediatric parotid neoplasms were malignant with Mucoepidermoid carcinoma is the commonest and 41.5% were benign; were the most frequent was the pleomorphic adenoma.
