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.

Mucocele of the appendix is uncomrnon and rarely diagnosed preoperatively. The malignant rountpart-i.e. mucinous cystadenocarcinoma--has the same grross appearance and many micro scopic features in cornmon wilhe the benign form. It rnay be associated with ovarian mucinous cystadenoma of strikingly similar microscopic appearence. A serious complication is a rupture of the mucoeele resulting in pseudomyxoma peritonei. Each case of benign and malignant mucocelr of the appendix falsely diagnosecl as an oovarian tumor before laparotxumy are presented wilh a brief rieview of the literatures.

Pseudomyxoma peritonei is a rare condition characterized by mucinous ascites associated with peritoneal and omental implants. This is most commonly originated from mucinous tumor of the ovary or appendix. We have experienced a case of pseudomyxoma peritonei associated with borderline mucinous tumor of both ovaries and appendix. We concluded that the appendix is the primary lesion of pseudomyxoma peritonei by various immunohistochemical stains and therefore reporting this case with the brief review of literatures.
