A 89 year-old woman visited to our hospital with a complaint of right lower abdominal pain. Colonoscopic examination revealed a Isp type protruding lesion in 7mm diameter in lower rectum. We performed endoscopic mucosal resection to this lesion for accurate diagnosis because biopsy specimen revealed the atypical lymphocyte infiltration. Pathological findings of the resected tissue showed marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue type (MALToma) . Because of her age was high and the lesion located in the lower rectum without any other lymphoma lesions, we followed up this ulcer lesion with endoscopic examination. As Helicobacter pylori (HP) infection to her stomach was positive, we eradicated HP infection by triple therapy. After EMR to this rectal MALToma, she has not a relapse until today.
We suggested to be able to treat with EMR for gastrointestinal primary MALToma when its lesion was the indication for EMR and patient was senile and/or had any inoperable complications.
