Answer : D Metastatic carcinoma
Metastatic carcinoma is by far the most common malignant disorder affecting the peritoneum. Ovarian, gastric, and pancreatic carcinomas are particularly likely to seed the peritoneum, but any intra-abdominal
carcinoma can spread to the peritoneum.
Metastatic carcinoma to the abdomen presents in the form of multiple
serosal nodules and ascites fluid that contains malignant cells.
