Description
The specimen shows fallopian tube and ovary; the latter is greatly enlarged by tumour; the cut
surface of the tumour shows that it is mainly solid, but with a number of cysts around the periphery
in which there is gelatinous material. At one point towards the lower pole the tumour appears to
have escaped the serosa, but elswhere the tumour is confined.
History
The woman presented with abdominal pain and diarrhoea leading to a diagnosis of bowel
obstruction secondary to a pelvic mass. Exploration disclosed a left-sided ovarian tumour and a
carcinoma of the sigmoid colon. The histology of the colonic lesion and the ovary differed
sufficiently for one to assume that these were different primary tumours.
