Pathological evidence shows that PIOSCC originates from the residual odontogenic epithelium and a preexisting odontogenic cyst or tumor. Here, we report the case of a 63-year-old man with central squamous cell carcinoma of the mandible. On the basis of imaging and histopathology reports, the patient was diagnosed with PIOSCC of the jaw. Subsequently, he was treated with postoperative adjuvant chemotherapy. During a postoperative follow-up visit in the ninth month, mandibular computed tomography (CT) scanning and bone imaging revealed local recurrence and condylar invasion. Therefore, radiation along with chemotherapy was administered. This case study adds to the literature on PIOSCC and widens the understanding of its diagnosis, treatment, and prognosis.展开更多
