| Sigmoid carcinoid |
 |
 |
|
Two sigmoid carcinoids in a 55 year old patient. The tumors are hormonally inactive
and both 1,5 cm in diameter. In the right picture a necrosis on top of the tumor is visible.
Carcinoids may occur as single tumors or at multiple locations within the gastrointestinal tract
but also in the brochial tree. Rectum and the appendix are very frequent sites of occurrence.
Both tumors are larger than 1 cm and are resected surgically. |
| Rectal carcinoid |
 |
Small probably submucosal rectal tumor.
Histology reveals a rectal carcinoid.
Further tumor staging doesn´t show other tumor
locations. The rectal tumor is resected endoscopically
after adrenalin injection. |
