Multiple distant organ metastases from squamous cell carcinoma of the lower gingiva that followed a rapid course: An autopsy case report

We experienced a rare case, which was distant organ metastatic squamous cell carcinoma (SCC) and had deteriorated rapidly. An 80-year-old man was transported to hospital because of a sudden loss of consciousness. A tumor was found in his right mandibular gingiva, which was histopathologically diagnosed as SCC. A large tumor was detected in the pelvic soft tissue on a thoracoabdominal computed tomography scan. The patient died on the 22nd day after he was admitted to hospital. We performed an autopsy. The autopsy revealed multiple distant organ metastases, and all of the lesions were histopathologically diagnosed as SCC.
