RESUMO
Primary Peritoneal Serous Papillary Carcinoma has a diffuse involvement of peritoneum in the absence of an obvious primary site and is very rare. It is histologically identical to ovarian serous papillay carcinoma but involves the ovarian surface mimimally, or spare the ovaries. Clinically it is impossible to differentiate with other tumor originated from peritoneum and ovarian carcinoma because of the similarity of clinical presentation and course. Primary Peritoneal Serous Papillary Carcinoma was first described by Swerdlow in 1959 and then has been very rarely reported in literatures. A few cases were reported in Korea. We have experienced a case of Primary Peritoneal Serous Papillary Carcinoma and report this case with a brief review of concerned literatures.
