This is an incidental intraoperative finding of an appendiceal mucocele. Mucocele of the appendix is an uncommon tumour and is characterized by obstructive dilatation of the appendiceal lumen by intraluminal accumulation of mucinous secretions. Mucocele may be associated with a malignant process; therefore, complete resection without rupturing the mucocele is essential to prevent pseudomyxoma peritonei, a spread of the malignant cells into the peritoneal cavity with mucinous deposits. This patient underwent an open appendicectomy to ensure complete resection and has recovered well from the surgery. Histology confirmed mucocele of the appendix with clear margins.
