Advanced papillary adenocarcinoma of unknown origin as tumor previa during late pregnancy.

A 41-year-old woman with advanced abdominal adenocarcinoma presented at term pregnancy. The tumor was presented as previa and obstructed the delivery. A cesarean section was performed and a healthy child was born. At surgery diffuse metastatic disease was detected throughout the pelvis and abdomen and was partially resected. Combined chemotherapy consisting of cis-platinum, adriamycin and cytoxan was administered for 5 months. At second-look laparotomy no residual disease was found. We present an unusual presentation of metastatic abdominal undifferentiated carcinoma treated as ovarian cancer.
