Background & Objective: Low-grade appendiceal mucinous neoplasm (LAMN) is a very rare condition, diagnosed in 0.2-0.7% of appendectomies. The pathophysiology of the neoplasm involves accumulation of large volume of mucin in the appendiceal lumen, resulting in its obstructive dilation. Most epithelial tumors affecting the appendix are of the mucinous type and are manifested by mucin accumulation within an inflamed appendix with fibrotic and hyalinized wall.Case Presentation: A 29-year-old female presented with a history of chronic and intermittent episodes of abdominal pain and a palpable mass in the right lower abdominal quadrant. Sonography showed a 58 mm mass anterior to the uterus and adjacent to the ovary, probably a uterine myoma. Laparotomy revealed normal uterus, and ovaries with a translucent mass originating from the appendix and fixed to the cecum. Pathologic examination of the mass was reported as low grade appendiceal mucinous neoplasm.Conclusion: This is a rare case of appendiceal mucocele in a young female, mimicking a pelvic mass, which was misinterpreted by sonography as a gynecologic solid mass near the uterus. Preoperative diagnosis of appendiceal mucocele is important due to the risk of concurrent GI and ovarian malignancy associated with the condition.

Abstract
Pseudomyxoma peritonei (PMP) is characterized by mucinous ascites in the peritoneal cavity and might involve the omentum and peritoneum. The PMPs originating from the ovary are mostly caused by ruptured ovarian mature teratomas and mucinous ovarian carcinomas. The present case is a rare advanced mucinous ...

Pseudomyxoma peritonei (PMP) is characterized by mucinous ascites in the peritoneal cavity and might involve the omentum and peritoneum. The PMPs originating from the ovary are mostly caused by ruptured ovarian mature teratomas and mucinous ovarian carcinomas. The present case is a rare advanced mucinous borderline ovarian tumor and late recurrence in PMP in a 52-year-old menopaused woman. She presented with gradual abdominal enlargement and cystic abdominopelvic lesion with internal septa and ascites. The patient underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, infracolic omentectomy, lymphadenectomy, and appendectomy. Histopathologic examination revealed mucinous borderline tumors. About 5.5 years after the first surgery, she presented with abdominal bloating and a sonography report of peritoneal seeding in the abdomen and pelvis. Abdominal exploration showed gelatinous-mucinous ascites and disseminated peritoneal carcinomatosis. The final histopathologic evaluation indicated PMP. Although the recurrence of mucinous borderline tumors is in an average of two years, the present case had relapsed after 5.5 years as pseudomyxoma with borderline pathology.
