Case report: Krukenberg tumours arising from a primary duodenojejunal adenocarcinoma

Abstract

We report a case of a bilateral Krukenberg tumour of the ovaries arising from a primary adenocarcinoma of the duodenojejunal flexure. Adenocarcinoma of the small bowel is uncommon, representing 1% of all primary malignant tumours of the gastrointestinal tract [1]. Krukenberg tumours arising from a primary duodenojejunal adenocarcinoma are even more unusual. To our knowledge there are less than five reported cases in the English literature [2,3]. Mazur et al. reviewing 325 cases of metastases to the female genital tract over 31 years, found only one case of ovarian metastasis from a primary small bowel carcinoma [2]. Most small bowel adenocarcinomas tend to metastasize to regional lymph nodes and the liver.
