Malignant ascites with omental metastasis: a rare event in prostate cancer

Prostate cancer is the most common type of male malignancy in the world and approximately 10-20% of prostate cancer shows a metastatic disease at initial diagnosis commonly to the bones, vertebrae, ribs, long bones, and skull. However, prostate cancer metastasis to the omentum with malignant ascites is extremely uncommon. In this study, we report such a case, which also highlights a repeatedly negative ascetic fluid cytology even with multiple omental metastatic nodules. The purpose of this case report is to provide awareness to physicians for this rare occurrence.
