Missed Diagnosis of Oral Cancer Leads to Severe Facial Deformity

Case Overview

This case involves a fifty-six-year-old woman who presented to her dentist with complaints of a lesion on her inner cheek. The mass measured about three centimeters long and extended past the jaw line. Her dentist was concerned over the visible morphology of the lesion and subsequently referred the patient to an oral pathologist for a biopsy to be performed on the area of interest. The patient arrived for the procedure but the oral pathologist simply diagnosed her with Lichen Planus and treated her with oral steroids. Several weeks later, the patient’s condition worsened and she returned to her primary dentist, however, no biopsy was performed. The dentist did not examine the lesion, nor did he communicate with or receive any report from the oral pathologist regarding his findings. The patient returned a week after her dental work with an abscess in the right gum, and a biopsy was performed in the right mandibular gingival region. The report finally revealed a buccal mucosa squamous cell carcinoma. Because of the delay in diagnosis and treatment, the patient had to undergo a right selective neck dissection, a composite resection of the right buccal mucosal tumor with marginal mandibulectomy, and a tracheotomy with lateral floor mouth reconstruction. Following the procedures, the patient suffered from severe dry mouth, little salivary function, and the inability to open her mouth fully to eat normal meals.
