case_images: Contrast-enhanced computed tomography (CT) scan of the abdomen and pelvis revealed large ascites with a mass effect, omental caking, and focal peritoneal soft tissue lesions, raising concerns of peritoneal carcinomatosis (Figure 1).

case_images: The patient underwent diagnostic laparoscopy (Figure 2), peritoneal biopsy, abdominal washout, and right subclavian chemoport placement.
case_images: Histology slides showing abundant mucin dissecting through the fibroconnective tissue, with focal scattered fragments of mucinous glandular epithelium showing low-grade cytology. No infiltrative type of invasion or desmoplastic reactions are seen. The histological findings are most consistent with a low-grade mucinous neoplasia/carcinoma in the setting of pseudomyxoma peritonei.
