Low-Grade Appendiceal Mucinous Neoplasm and Acute Appendicitis. Clinical Case Report

Abstract Low-grade appendiceal mucinous neoplasm corresponds to a rare histopathological lesion of the vermiform appendix and is considered even rarer when it manifests as an acute appendicitis. A clinical case of a 37-year-old female patient, with no clinical or surgical history, no allergies, is presented, who went to the emergency service by acute appendicitis chart and after surgery an appendicular mucocele was obtained, this is a generic terminology that has been the subject of controversy for its concept, histopathological classification and postoperative clinical evolution. Also discussed is open versus laparoscopic handling, several authors exclusively recommend open handling, because in laparoscopic management they report an increased risk of accidental opening of the surgical part with the subsequent possibility of developing Pseudomyxoma Peritonei. Some series of cases report laparoscopy as a treatment considering the dimensions of the appendix and the expertity of the surgeon. Clinical follow-up is very important considering possible condition to neighboring organs, disease progression and other possible complications; it is done at 6, 12 months and 5 years; with analysis of complementary laboratory, imaging and endoscopic examinations. According to this result is determined a medical or surgical treatment. Keywords Appendicular Mucocele; Low-Grade Appendiceal Mucinous Neoplasm; Pseudomyxoma Peritonei
