This 17-centimeter serous cystadenocarcinoma was discovered during exploratory laparotomy of a woman who presented with intestinal obstruction, which was caused by extrinisic compression of the bowel by one of the many intra-abdominal metastases of this tumor. Grossly, the tumor's cut surface demonstrates both cystic and papillary architectural patterns.

The photo was taken with an Olympus D-600L digital camera on a copy stand illuminated by 4 photofloods. The specimen had been fixed in formalin overnight and immersed in 70% ethanol shortly before it was photographed.
