Bilateral ovarian masses, massive ascites, and prior appendectomy: must it be ovarian cancer? ——a case report of pseudomyxoma peritonei 24 years after appendectomy

1

A 56-year-old female developed bilateral ovarian masses and massive ascites 24 years after an appendectomy, raising suspicion for ovarian cancer.
2

Intraoperative findings revealed the abdominal cavity filled with yellow gelatinous material, leading to a diagnosis of pseudomyxoma peritonei (PMP).
3

Pathology confirmed the ovarian masses as mucinous tumors of gastrointestinal origin, highlighting the rarity of ovarian metastasis from such tumors.
4

Pseudomyxoma peritonei is characterized by gelatinous fluid accumulation and is primarily associated with appendiceal tumors, not ovarian tumors.
5

The case emphasizes the need for long-term follow-up in patients with a history of appendectomy due to the potential for rare metachronous presentations of PMP.
