Abstract :Gingival squamous cell carcinoma is an uncommon malignancy of the oral cavity, which can simulate benign inflammatory conditions such as periodontal diseases. Gingival squamous cell carcinoma is usually diagnosed late and has a relatively poor prognosis because the involvement of underlying bone is present at early stage and misdiagnosis or delayed diagnosis after invasive procedures is common. In this case, we report a 57-year-old male patient who presented with a non-healing wound for 8 months after extraction, which was subsequently diagnosed as squamous cell carcinoma.
