Low grade appendiceal mucinous neoplasms are a challenging entity not just due to their innocent appearance and aggressive extension but also due to their origin dilemmas. We present one such interesting case in a 35-year-old Saudi female who presented to King Abdulaziz University Hospital with acute abdominal pain. Th e patient presented with the main bulk of the mucinous tumor in the left ovary with extensive pseudomyxoma peritonei. Incidentally there was also a mature cystic teratoma in the same ovary. Appendiceal origin was confi rmed on histology and immunohistochemistry. In conclusion our case scenario of low grade appendiceal mucinous neoplasms with concomitant ovarian mucinous tumor, mature cystic teratoma and pseudomyxoma peritonei suggests appendiceal origin both on morphology and immunohistochemistry. As such routine excision of appendix in these case scenarios remains a valid consideration.

Progressive Accumulation

Abstract A mucocele refers to an appendix that has dilated due to progressive accumulation of mucus within its lumen. Appendiceal mucocele is a rare cause of an acute abdomen. They represent 0.2-0.7% of all appendix specimens. LAMN account for less than 0.3% of appendicectomy specimens.  We present a 38 year old man with an acute RIF’s pain who went on to have CT scan which revealed a mucocele of appendix but did not show any features of perforation or pseudomyxoma peritonei. He had a laparoscopic converted to open appendicectomy. The proximal 2 cm of appendix was oedematous but normal calibre. Histology revealed a low grade appendiceal mucinous neoplasm (LAMN) that was completely excised.  The mucocele of the appendix was first described by Rokitansky in 1842. Appendix mucocele may come as a consequence of obstructive or inflammatory processes, cystadenomas or cystadenocarcinomas. Appendiceal mucinous neoplasms commonly presents in the sixth decade of life and our patient was much younger in comparison. Several literatures suggest the value of preoperative CT imaging in obtaining diagnosis and also in planning further treatment. Appendicectomy or a right hemicolectomy is treatment of choice based on presence or absence of following factors 1. Perforated mucocele 2. Involvement of the base of the appendix. 3. Positive lymph nodes of mesoappendix and ileocolic. Patients with malignancy or pseudomyxoma peritonei are likely to require cytoreductive surgery, heated intraoperative intraperitoneal chemotherapy, early postoperative intraperitoneal chemotherapy.

Classification Management

Primary appendiceal mucinous lesions are uncommon and represent a spectrum from nonneoplastic mucous retention cysts to invasive adenocarcinoma. Low-grade appendiceal mucinous neoplasms (LAMNs) represent an intermediate category on this spectrum and can be classified according to whether or not they are confined to the appendix. Although LAMNs are frequently confined to the appendix, they can also spread to the peritoneum and clinically progress as pseudomyxoma peritonei (i.e., mucinous ascites). Thus, the appropriate classification of appendiceal primary neoplasia is essential for prognosis and influences clinical management. In addition, the precise classification, management, and clinical outcome of patients with disseminated peritoneal disease remain controversial. Here, we report an unusual case of LAMN with pseudomyxoma peritonei that initially presented with mucinous and bloody vaginal discharge. Pathological evaluation revealed low-grade appendiceal mucinous neoplasm with secondary involvement of the peritoneum, ovaries, and endometrial surface. Therefore, LAMN should be considered in the differential diagnosis of mucinous vaginal discharge.
