Herein we describe a case of mucosa‐associated lymphoid tissue (MALT) lymphoma of the cecum and rectum with the Leser–Trélat sign. A 76‐year‐old Japanese woman was admitted to the Harima Hospital of Ishikawajima‐harima Heavy Industries, Health Insurance Society for hematochezia. Colonoscopy showed two large elevated tumors, one in the cecum and the other in the rectum. Biopsy was not diagnostic. Endoscopic snare loop biopsy specimens from both tumors were diagnosed as MALT lymphoma. After staging to IIE, the patient underwent surgery. Macroscopically, the cecal tumor was elevated with a large and deep depressed region, measuring 40 × 35 mm. The rectal lesion was a large elevated tumor, measuring 80 × 70 mm. Histologically, both tumors were diagnosed as MALT lymphoma and there was no lymph node metastasis. The patient received chemotherapy and there is no evidence of recurrence 1 year after surgery. We present this case to show that colorectal MALT lymphoma can present as a large tumor, even in early clinical stages, that multiple lesions should be anticipated and that surgical treatment is needed in these cases.
