Soft tissue tumor case studies

Objectives: The odontogenic adenomatoid tumor (AOT) has a prevalence of 3% to 7% among odontogenic tumors. There are 3 variants of AOT: follicular, extrafollicular, and peripheral. The present study aims to trace the clinical and epidemiologic profile of extrafollicular AOT, based on a review of case reports. Study Design: Using the adenomatoid and extrafollicular descriptors, a search was performed in the PubMed database. Fifty-one articles were obtained as a result. The following exclusion criteria were adopted: by title, by case report, by the summary, and by the series of cases. At the end, 10 articles were used as sources for the present study. Results: Ten cases were published between 2009 and 2019, with the following most prevalent characteristics: Asian ethnicity (90%), no gender preference, and mandible location (60%). Imaging presentation included well-defined borders (80%); root displacement (50%); presence of cortical perforation (30%); and root resorption (30%). The mean time of the cases was 4 months, with a maximum of 2 years, and no recurrence was observed in any of the cases. Conclusion: Extrafollicular odontogenic adenomatoid tumor is uncommon. It does not present a predominant profile, exhibiting a diversity of clinical manifestations, with slow to fast and locally aggressive growth.
