“…During pregnancy, the incidence of malignant neoplasms is low. While there have been cases of appendiceal malignancies complicating pregnancy, these reports are rare [2][3][4][5]. Over half of these cases involve neuroendocrine tumors, which are commonly identified due to their associated carcinoid syndromic presentation [6,7].…”

Introduction: Appendiceal neoplasms comprise a low percentage of gastrointestinal malignancies. These malignancies are most often noted incidentally on imaging or during surgery. There are few case reports describing malignancy of the appendix during pregnancy and even fewer that involve abnormal pregnancies, such as molar or ectopic pregnancy.Case Report: This is the case of a 32-year-old female who presented with an unknown last menstrual period (LMP), positive home pregnancy test, and right adnexal mass. Due to the concern for ectopic pregnancy, she underwent laparoscopic assessment, revealing an appendiceal neoplasm. She was subsequently diagnosed with a concurrent molar pregnancy. Conclusion:Given the proximity of the appendix to right-sided adnexal structures, appendiceal tumors can be mistaken for ovarian masses, or vice versa. Appendiceal adenocarcinoma often presents with symptoms of acute appendicitis and can mimic the pain of a ruptured ectopic pregnancy in reproductive aged women. Therefore, it is important for clinicians to consider involvement of both structures while evaluating an adnexal mass. Ultrasound imaging is the standard of care for women presenting with pelvic pain and an elevated b-hCG; however, alternative imaging modalities should be considered when ultrasound findings are not definitive.

Key Clinical Message We describe the different clinical presentations, radiology, histology and management of this unique, highly aggressive disease. Clinical presentation of appendicitis may not just be appendicitis. Appendiceal tumors must always be considered in the differential diagnosis. Dedicated radiology and histological examination in addition to aggressive surgical and oncological input improve outcome.

Background. Clinical decisions in patients with peritoneal dissemination of low-grade appendiceal mucinous neoplasms (LAMN) diagnosed during pregnancy are challenging. However, their slow progression and favorable prognosis allow deferring definitive treatment until after spontaneous delivery, a reasonable period of breastfeeding, and fertility preservation. Case Presentation. Two pregnant patients were incidentally diagnosed with LAMN and extensive peritoneal spread at 20 weeks gestation and at cesarean section. Treatment with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in both cases was delayed until spontaneous delivery at term and breastfeeding in the first patient and breastfeeding and fertility preservation in the second patient. Both patients remain disease-free for over 5 years, and their children are healthy. The literature review highlights the challenges that physicians face in treating pregnant patients with stage IV appendiceal tumors. Conclusion. Pregnancy management decisions in patients with peritoneal spread from mucinous appendiceal tumor should be based on understanding the tumor biology and prognosis. Definitive treatment in pregnant patients with favorable tumors, such as LAMN, may be delayed until spontaneous delivery without compromising maternal survival.
