Abstract:
Villous adenoma of the appendix is a rare neoplasm and intussusception of the appendix is a rare pathologic condition. A very rare case seen in a 35-year-old male with pain in the right lateral abdomen is reported. In this patient, the appendix along with the villous adenoma intussuscepted and invaginated into the cecal lumen, and presented as cecocolic intussusception. A polypoid lesion was diagnosed in the cecum by fiberoptic colonoscopy. Unlike polypoid lesions at other sites in the large intestine, polypoid lesions of the cecum may accompany intussusception and invagination of the appendix. Consequently, caution is required in performing endoscopic polypectomy in cases of polypoid lesions of the cecum.
Insights
A rare case of appendiceal intussusception caused by a villous adenoma is presented. This rare condition highlights the need for caution during endoscopic polypectomy of cecal lesions.
Area of Science:
- Gastroenterology and Surgical Oncology
Background:
- Villous adenoma of the appendix is an uncommon neoplasm.
- Appendiceal intussusception is a rare pathological condition.
Observation:
- A 35-year-old male presented with right lateral abdominal pain.
- Fiberoptic colonoscopy revealed a polypoid lesion in the cecum.
Findings:
- The patient experienced intussusception of the appendix, containing a villous adenoma, into the cecal lumen.
- This resulted in a cecocolic intussusception presentation.
Implications:
- Polypoid lesions in the cecum can be associated with appendiceal intussusception and invagination.
- Endoscopic polypectomy of cecal polypoid lesions requires careful consideration due to this risk.
