The ratio of men to women is about 2: 1. Generally, it   is admitted that 60% of carcinoma of the mandibular gingival are located in the posterior of premolars. Gingiva is one of the less common sites of oral squamous cell carcinoma (OSCC). Due to the variable clinical and behavioral presentations, it can easily be misdiagnosed as benign neoplasms or other inflammatory reactions. We encountered a 76-year-old woman with an unusual OSCC on the anterior mandibular ridge, imitating inflammatory hyperplastic (IH) lesion in May 2013. She complained that her denture was not seated suitably because of a mandibular lesion. After biopsy of the lesion, the surgeon noticed that real bone resorption was not visible in the x-ray image. Then histopathological evaluation detected the OSCC. Patient was referred to the CT-Scan and MRI. Three months later, the lesion recurred, enlarged and extended rapidly and she was emphasized the importance of a secondary surgery in a timely fashion.. She did not accept and then underwent radiotherapy and chemotherapy. In November 2013, the patient passed away because of the progress of OSCC. This case reminded us to keep the possibility of oral SCC in mind while examining every intra-oral lesion.   UR - https://jdmt.mums.ac.ir/article_5178.html L1 - https://jdmt.mums.ac.ir/article_5178_1d3944c4c08e4e5034e5ef7cfeba391f.pdf ER -
