A 72-year-old man previously presented with obstructive bowel symptoms. He was diagnosed with mantle cell lymphoma—a type of non-Hodgkin lymphoma—with involvement of the rectosigmoid junction and terminal ileum.
He underwent a left hemicolectomy and resection of the terminal ileum followed by chemotherapy (fludarabine, mitoxantrone, dexamethasone and rituximab). After treatment he went into prolonged remission and follow-up colonoscopies 5 years and 7 years later were both unremarkable. The findings of a gastroscopy and capsule endoscopy were also normal 7 years after treatment, at which time the patient was asymptomatic with normal blood results. His haematologist requested a surveillance FDG PET-CT scan, which demonstrated a hot spot in the descending colon (figure 1). A further colonoscopy was carried out and showed 2 polyps in the descending colon (figure 2; DC1 [15mm] and DC2 [50 mm]). The ileocolonic anastomosis and neoterminal ileum were both unremarkable.
WHAT WOULD YOU DO WITH THESE POLYPS?
a) Ignore them, as they are inflammatory.
b) Take biopsy samples only.
c) Perform standard snare polypectomy.
d) Organise an endoscopic mucosal resection (EMR).
e) Organise an endoscopic submucosal dissection (ESD).
