Lymphoid cysts (cystic lymphangiomas) of the colon
Colon cyst 4 – Example
This 76-year-old retired white male was referred for work-up of microcytic anemia and abdominal pain. Blood loss via the gastrointestinal tract was not observed and not detected. Ultrasound and gastroscopy returned no pathological findings.
The videoclip begins in the sigmoid colon. One sees a cystic tumor filling the lumen of the colon. It is covered with normal mucosa and has a perfectly smooth surface. Passage of the site of the tumor with the endoscope is not hindered. Pressure applied by the biopsy forceps causes slight indentation of the surface.
A tumor such as this, with smooth surface and no ulceration, cannot be held responsible the patient’s anemia. No therapy was recommended. The consistency of the tumor suggests a cyst, less probably as lipoma.
