title: Metachronous multiple carcinoma of lip after surgery for gingival carcinoma: a case report.
abstract: A case of multiple carcinoma of the lower lip probably induced by repeated bite trauma due to lack of sensation is reported. A reduction in immunocompetence by carboplatin (CBDCA) might be an additional condition for the carcinogenesis. This case suggests that the reconstruction of the sensory nerve is important after resection of a malignant tumor of the head and neck region.
