Rationale:
Cases of intussusception caused by mucinous carcinoma have been rarely reported, and those caused by colonic mucinous adenocarcinoma (MAC) with distant metastasis were even fewer.
Patient Concerns:
A 60-year-old woman who complained of severe pain around the navel with nausea and vomiting for a week was admitted on November 28, 2017. There were multiple watery stools and abdominal pain was worsened over the prior week.
Diagnosis:
She was diagnosed by abdominal computed tomography, current medical history, and abdominal signs. Her initial diagnosis was acute abdomen, intussusceptions, and intestinal obstruction. The final diagnosis was MAC, which was based on postoperative pathology.
Interventions:
The patient received emergency laparotomy, followed by 5 courses of chemotherapy with oxaliplatin plus capecitabine, and then 6 courses with 5-fluorouracil + oxaliplatin + calcium leucovorin.
Outcomes:
The patient was in good nutritional condition, and no obvious tumor recurrence or metastasis was found until July 9, 2018.
Lessons:
Even though the prognosis of colonic MAC is poor, being able to receive timely surgical treatment, good nutritional status and reasonable postoperative chemotherapy are the key factors to prolonging patient's survival.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
