Lymphatic cysts (cystic lymphangiomas) of the colon
Colon cyst 1 – Example
This 67-year-old white male patient with iron deficiency anemia was referred for colonoscopy, which identified a tumor about 2 cm in diameter covered with normal mucosa. It was soft and the overlying mucosa appeared very thin.
The videoclip shows the small tumor. Manipulation with the biopsy forceps revealed it to be soft and easily indented. The overlying mucosa appeared thin and translucent. Bridge folds are seen at the transition to the bowel wall. As a result of biopsy, the cystic tumor was opened and drained.
These small cysts are as amenable to endoscopic removal as is the case with polypectomies. Because malignancy was not suspected, this small tumor could be left untreated. It is most probably not responsible for the patient’s iron deficiency anemia.
