Recurrent, oral cavity tumor-like exophytic lesions mimicking neoplastic disease in a patient with history of human papillomavirus-mediated squamous cell carcinoma.

Reactive hyperplasia is a phenomenon responsible for exophytic lesions in the oral cavity, and may appear to be suspicious, especially in patients who have a significant history of malignancy. Here, we present a case of reactive hyperplasia mimicking recurrence in a patient who was previously treated for tonsillar carcinoma. Physicians who commonly see patients with oral lesions, particularly oral surgeons and otolaryngologists, should be cognizant of the unusual presentation of these lesions as they may mimic the physical characteristics of recurrence.
