Abstract:
A CAT-scan-guided biopsy of the retroperitoneal tumor of a 54-year-old female revealed a serous adenocarcinoma resembling a serous adenocarcinoma of ovarian origin. Partial response to platinum-based chemotherapy was observed. Exploratory laparotomies and an autopsy found no possible primary lesion for the tumor. Therefore, we concluded that this tumor is a primary serous adenocarcinoma of the retroperitoneum. Although further accumulation of cases is required, it appears that primary treatment for serous adenocarcinoma of the retroperitoneum is platinum-based chemotherapy if surgical removal is incomplete.
