This condition is regarded as worrisome because it may be associated with malignancies. Case: A 34-year-old female patient referred to the clinic with complaint of paresthesia in right lower lip. A lytic lesion involving the inferior alveolar nerve was detected on radiographic examination. Biopsy was done under local anesthesia. After the histopathological examination of the sample the diagnosis of adenocarcinoma was made. The patient was then referred to the department of oncology. As a result of the examinations, it was found that the primary cause was lung adenocarcinoma. Conclusion: This case report emphasizes that patients with NCS should be evaluated very carefully because this condition may be a symptom of a systemic malignancy.}, number={1}, publisher={Süleyman Demirel University}
