Final Diagnosis -- Carcinoid tumor arising in a Meckel's
- FINAL DIAGNOSIS:
- ILEUM, SEGMENTAL RESECTION -
- CARCINOID TUMOR ARISING IN A MECKEL'S DIVERTICULUM.
- Meckel's diverticulum is one of the most common congenital
anomalies of the gastrointestinal tract. Most Meckel's
demonstrate ectopic gastric mucosa. Additionally, one can see
pancreatic or colonic mucosa. Symptoms can be related to rupture
of the diverticulum, secretion of ectopic gastric or pancreatic
hormones, or intussusception (with the diverticulum as the
- A 1992 review (1) lists 104 cases of carcinoid tumor arising
in Meckel's diverticulum reported in the world literature.
Most of these showed the tumor present in the tip of the
diverticulum. The majority of patients are asymptomatic. A few
become symptomatic from the diverticulum and/or the carcinoid
tumor itself. Only ten of these cases developed the "carcinoid
syndrome". Metastasis of the carcinoid tumor is related to size.
Those tumors greater than 2.0 cm all had metastatic foci.
