Rationale:
Appendiceal mucinous tumors with intussusception are extremely rare. As primary lesions, malignant tumors often present with atypical clinical symptoms, which increases the likelihood of misdiagnosis.
Patient Concerns:
A 79-year-old female patient of Miao ethnicity in Guizhou Province, China, was admitted with intermittent paroxysmal abdominal pain for 20 days and abdominal distension for 3 days.
Diagnoses:
Computed tomography revealed ileal intussusception in the lower abdomen, suspected to be associated with a tumor.
Interventions:
Laparoscopy-assisted right hemicolectomy was performed.
Outcomes:
Postoperative histopathology showed a low-grade appendiceal mucinous tumor with mucinous components extending into the muscularis propria and localized calcification. Regular follow-up was recommended.
Lessons:
Low-grade appendiceal mucinous tumors are extremely rare and are even less common when complicated by intussusception. Their clinical presentation is nonspecific, which may result in missed diagnosis. Therefore, thorough preoperative evaluation and careful surgical planning are essential for improving prognosis and minimizing the risk of severe complications.

01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
