A Rare Case of Low-grade Appendicular Mucinous Neoplasm Presenting as Ileocolic Intussusception

Abstract

Appendiceal mucinous neoplasms are rare and account for just 0.6 percent of gastrointestinal malignancies and approximately 0.7-1 percent of appendicectomy specimens. Most of the appendicular malignancies are detected incidentally. We, herein, report images of a case of a 76 years old male patient who presented with dull pain in the lower abdomen and a palpable lump in the right lower abdomen. A contrast enhanced computed tomography scan of the abdomen revealed an ileo-colic intussusception. He underwent a laparoscopic quarter colectomy with ileo-colic anastomosis followed by an uneventful post-operative recovery. The histopathology report revealed a low grade appendiceal mucinous neoplasm with clear resecton margins.
