Abstract

Introduction: Most tumors of salivary glands appear as a solitary mass in a single gland. It's extremely rare to have a case where tumors with different characteristics develop and coexist. Case Report: Our patient is a 38-year-old female, a known case of low-grade Mucoepidermoid Carcinoma (MEC) of the hard palate. The tumor was resected in 2019. After three years, she complained of left-sided submandibular swelling for the past 7 years. On January 31st, 2023 excision of the mass was performed, and the final surgical pathology turned out to be Adenoid Cystic Carcinoma (ACC). Conclusion: Despite the rareness of metachronous occurrence of salivary gland cancer with different anatomic locations and histopathology, it is still encountered in medical practice. Here, we emphasize the importance of follow-up with periodic clinical and radiological examinations.
