1State Key Laboratory of Oral Diseases & National Clinical Research Center for Oral Diseases & Dept. of Head and Neck Oncology, West China Hospital of Stomatology, Sichuan University, Chengdu 610041, China.
Summary
Multiple parotid gland tumors are rare. This case study details a unique instance of simultaneous bilateral pleomorphic adenoma and basal cell adenoma, offering insights into these uncommon salivary gland neoplasms.
Area of Science:
- Otolaryngology
- Head and Neck Surgery
- Surgical Pathology
Background:
- Parotid gland tumors are typically solitary, with multiple occurrences being exceptionally rare.
- Pleomorphic adenoma and basal cell adenoma are common and rare salivary gland tumors, respectively.
Observation:
- This report describes an extremely unusual case of bilateral and simultaneous pleomorphic adenoma and basal cell adenoma in the parotid glands.
- The presentation involved synchronous tumors affecting both parotid glands.
Findings:
- The coexistence of pleomorphic adenoma and basal cell adenoma in a bilateral and simultaneous manner is highly atypical.
- Diagnostic challenges and therapeutic considerations for these rare parotid gland tumors are highlighted.
Implications:
- This case expands the understanding of multifocal and synchronous salivary gland tumors.
- It underscores the importance of thorough diagnostic evaluation for rare parotid gland neoplasms and informs treatment strategies.
