[Acute abdomen due to perforated appendicular mucocele]. / Abdomen agudo por mucocele apendicular perforado.

Primary neoplasms of the appendix are present in approximately 0.2% to 0.3% of appendectomy specimens. Generally affect middle-age adults and elderly people. Approximately 30% to 50% of appendiceal neoplasms manifest with acute appendicitis by luminal obstruction. The definitive diagnosis is histological. We must avoid simple laparoscopic appendectomy and adopt an open procedure with a laparotomy appendectomy for a bening process. Right hemicolectomy is indicated when a malignant condition is suspected Follow-up is recommended in this pathology due to the risk of associated malignant neoplasms. We report a case of perforated appendiceal mucocele in a 84-year-old man presented as an acute abdomen.
