Adenocarcinoma papilar seroso primario del peritoneo

A clinical case of primary peritoneal serous adenocarcinoma is presented. A woman 66 years old with abdominal pain and ascitis. Clinical, radiologic and cytology data suggested a peritoneal carcinomatosis of an unknown primary adenocarcinoma. Laparotomy and definitive histopathological findings show a müllerian primary peritoneal serous adenocarcinoma with normal ovarian stromal tissue. A similitude with stage III ovarian adenocarcinoma has led to the Gynecologic Oncology group to make a criteria for these neoplasia: normal ovarian size; non ovarian stromal tissue affectation; more extraovarian disease; histopathology of a papillary serous carcinoma. Nevertheless the correct treatment for these type of tumor is the same as that of the ovarian adenocarcinoma.
