上顎歯肉癌に対する頸部郭清術により発見された子宮体癌からと考えられた頸部リンパ節転移の1例 A case of cervical metastasis suspected to be from cancer of uterine body detected on neck dissection in a patient with upper gingival cancer
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.
