Summary
Pediatric salivary gland tumors include pilomatrixomas, a benign skin appendage tumor. Early diagnosis via clinical assessment and ultrasound-guided fine needle aspiration cytology is crucial for appropriate management.
Area of Science:
- Oncology
- Pathology
- Pediatric Surgery
Background:
- Great salivary gland tumors are rare in children.
- Pilomatrixoma, a benign skin appendage tumor, is an uncommon but significant cause of pediatric salivary gland masses.
Purpose of the Study:
- To review definitive histological diagnoses of pediatric great salivary gland tumors.
- To highlight the incidence and diagnostic considerations of pilomatrixomas in children.
Main Methods:
- Retrospective review of 12 pediatric patients (6 months to 18 years) with great salivary gland masses treated between 1995 and 2010.
- Analysis of clinical presentation, imaging, and fine needle aspiration cytology (FNAC) findings.
Main Results:
- Carcinomas predominated among true neoplasms (6/9), with low-grade mucoepidermoid and acinic cell carcinomas being most common.
- Pilomatrixoma was the most frequent benign diagnosis (2/6), accounting for 17% of all salivary gland lumps and 66% of benign neoplasms.
- Clinical findings included adherence to the skin but not underlying tissue.
Conclusions:
- Pilomatrixoma should be considered in the differential diagnosis of pediatric parotid region masses.
- Ultrasound-guided FNAC can strongly support the diagnosis of pilomatrixoma.
- Awareness of potential pilomatrixoma is essential for cytopathologists and surgeons to ensure proper sample handling and avoid unnecessary parotidectomy.
