Abstract

Primary serous papillary carcinoma of peritoneum (PSCP) is a tumor of the peritoneum, distinct from malignant mesothelioma, but similar in many ways to primary epithelial ovarian carcinoma (EOC). It seems to be histologically identical to EOC and is differentiated from EOC based on the extent of gross ovarian involvement and microscopic invasion of the cortex. Currently, PSCP is evaluated, staged and treated in the same fashion as EOC, with the Gynecologic Oncology Group trials for the treatment of EOC now open to patients with PSCP. Therefore it is managed surgically in the same way as EOC with shared goal of optimal cytoreduction. Although the preponderance of evidence supports the benefit of maximal cytoreductive efforts for EOC, only limited data are available for debulking in PSCP. Here we report four cases of PSCP with a short literature, in who excisions of all visible implants were performed and residual lesions were measured up to less than 2 cm.
