Squamous cell carcinoma of the oral cavity derived from a skin graft: A case report

Abstract

A case of oral cancer that had derived from a 19-year skin graft on the left buccal mucosa is reported. The patient had had three previous operations due to squamous cell carcinoma, erosion, and squamous cell carcinoma of the left buccal mucosa, respectively. In the last two operations, skin was transplanted, and the present cancer is believed to have derived from the latter one. The tumor was resected, and a new skin was grafted. In situ hybridization of human papilloma virus (HPV) was carried out; the HPV 16 DNA could not be detected in the specimen. Eight months later, a cervical lymph node metastasis was detected; thus, a radical neck dissection was performed.
