Pseudomyxoma Peritonei

Objectives: Pseudomyxoma peritonei (PMP) in women arises from an appendiceal or ovarian pathology and presents either of two histological subtypes of differing prognosis, disseminated peritoneal adenomucinosis (DPAM), or peritoneal mucinous carcinomatosis (PMCA). This study aimed to evaluate the demographic, clinical, and sonographic features among affected women and the differences between the two histological subtypes. Methods: A retrospective study was conducted involving 36 women with histopathological diagnosis of PMP who had preoperative ultrasound and underwent surgery at the department of obstetrics and gynecology in a tertiary hospital. Demographic and clinical data, ultrasound images and reports, and final histopathology were reviewed. To compare the subtypes, one‑way analysis of variance for continuous data and Chi‑square/Fisher exact test for categorical data were used, with P < 0.05 indicating statistical significance. Results: Patients were mostly >50 years of age, multigravid, and presented with abdominal distention. Ultrasound examinations consistently showed amorphous, mixed echo or echogenic ascites, peritoneal thickening, and omental caking. Adnexal/ovarian masses were detected in 66.7% of cases. Omental caking was significantly more prevalent in PMCA (83.3%; P = 0.0002), whereas larger ovarian tumors (>20 cm) and papillarities were more common in DPAM (both 92.9%; P = 0.0005). Most patients underwent gynecologic surgery (n = 31; 86.1%), and 14 (38.9%) required readmission due to recurrence. The final histopathology revealed largest tumor involvement of the appendix (n = 13; 36.1%), the ovaries (n = 11; 30.5%), or undetermined (n = 12; 33.3%). Conclusions Preoperative diagnosis of PMP is possible based on its clinical and ultrasound features. Although the subtypes are similar in most of these features, certain ultrasound findings may aid in distinguishing them.

Urachal mucinous tumor of uncertain malignant potential is very rare and is characterized by a multilocular cyst showing the proliferation of atypical mucin-secreting cells without stromal invasion. As in ovarian and appendiceal borderline tumors, it represents a transitional stage of mucinous carcinogenesis in the urachus. In addition, this tumor may recur locally and develop into pseudomyxoma peritonei. Due to its scarcity and diagnostic challenges, we report a mucinous tumor of uncertain malignant potential arising in the urachus.

Pseudomyxoma peritonei is a poorly understood condition characterized by mucinous ascites and multifocal peritoneal mucinous tumors. Pseudomyxoma peritonei is most commonly associated with mucinous tumors of the ovary and appendix. When two lesions are morphologically similar, it is difficult to determine whether one reflects a metastasis or whether the tumors are independent. Many studies concluded that most cases in which both the appendix and ovary were involved were primary appendiceal tumor with secondary involvement of the ovary, but we have experienced one case of pseudomyxoma peritonei originated from independent primary borderline mucinous tumors of the ovary and appendix. So we report this case with the brief review of literatures

"Pseudomyxoma peritonei is a clinical entity in which the peritoneal surface and omentum are involved with gelatinous, mucinous implants, and often massive gelatinous ascites. Most cases originate from ruptured ovarian mucinous cysts or appendiceal mucoceles, and involve only the intraperitoneal cavity. But there is much confusion about its etiology, clinical manifestation, treatment, and prognosis. We experienced a case of pseudomyxoma peritonei originating from the mucinous cystic tumor of borderline malignancy in unilateral ovary with rupture. A case of pseudomyxoma peritonei is reported with a brief review of the literature."
