Lymphatic cysts (cystic lymphangiomas) of the colon
Colon cyst 2 – Example
This 71-year-old white female patient was referred for screening colonoscopy. She did not report any abdominal complaints.
The cystic tumor in the sigmoid colon was indented using a probing instrument. It is covered with normal colon mucosa, which appears thin. The base is relatively narrow and resembles a pedicle.
This tumor is amenable in principle to wire excision. Because the patient reports no complaints, however, there is no clear indication for intervention. The patient was informed of possible symptoms and the tumor was left. The patient agreed to return immediately if she experienced abdominal pain or anal bleeding.
