소장의 종양은 매우 드물게 발생하며 그중 선암의 빈도가 가장 많고, 그 외에 악성흑색종, 유암종, 림프종, 육종 등이 주로 확인되었다. 원발부위가 자궁경부인 소장의 편평세포암 전이는 소장종양 중에서도 매우 드물며 자궁경부암의 소장 단독전이는 현재까지 한국에서 1예가 보고되었다. 본 저자들은 매우 드문 증례인 자궁경부암의 십이지장 전이와 이에 대한 고찰을 보고하는 바이다.

We report a case of duodenal metastasis from squamous cell carcinoma of the cervix confirmed by histopathological diagnosis. A 48-year-old woman was diagnosed with uterine cervix cancer stage IVB and underwent chemotherapy. During followup after chemotherapy, a mass suspicious of malignancy was found at the 3rd portion of the duodenum on the magnetic resonance imaging of the abdomen. Esophagogastroduodenoscopy with biopsy was done for an ulcerofungating mass at the 3rd portion of the duodenum. Squamous cell carcinoma was confirmed on the biopsy which was same as the histopathological diagnosis confirmed by cervix biopsy and right supraclavicular lymph node biopsy resulting from metastasis of cervix. Since 1981, only ten cases of small bowel metastasis from squamous cell carcinoma of cervix have been reported. It is exceedingly rare to find metastasis to the duodenum from uterine cervix cancer.
