Abstract

Improved therapy for cancer has resulted in many long-term survivors. Some of them may have a second cancer during long-term follow-up. The prevalence of multiple primary cancers has therefore increased, and many cases have been reported. However, cervical lymph node metastasis from both double cancers is rare.<BR>We describe a rare case of cervical lymph node metastasis suspected to have arisen from double primary cancers: an upper gingival cancer (squamous cell carcinoma: SCC) and a cancer of uterine body (adenocarcinoma: AC).<BR>Histopathological examination after radical neck dissection revealed SCC at levels I to III and AC at levels IV and V. AC in the neck resembled to the cancer of uterine body histopathologically. On the basis of these findings, the SCC at levels I to III was considered to be metastasis from the upper gingival cancer, whereas the AC at levels N and V was consistent with metastasis from the cancer of uterine body.
