We report a case of an enterocutaneous fistula resulting from drainage of a contained appendiceal perforation secondary to an obstructing appendiceal mucinous neoplasm. A 66-year-old otherwise healthy female patient proceeded to laparoscopic appendicectomy with resection of the fistula tract. Histopathology demonstrated a mid-appendiceal mucinous neoplasm, with a benign enterocutaneous fistula tract communicating with the distal, non-malignant portion of the appendix. We provide an overview of the literature and highlight the need to consider appendiceal mucinous neoplasm as a differential in the management of spontaneous right iliac fossa collections and fistulae.
