 A 61-year-old male patient who presented with diarrhea had undergone a total colonoscopy, was diagnosed as having plasmacytoma by biopsy, and then he visited our hospital. He was diagnosed as having primary isolated extramedullary plasmacytoma originating in the sigmoid colon, and was subsequently subjected to a laparoscopy-assisted sigmoidectomy with lymph nodes dissection. Histopathological findings demonstrated the proliferation of plasma cells from the lamina propia mucosae to the submucosal layer. Lymph node metastasis was not found, and thus, the patient was considered as a “curative resection” case. He has survived event-free for 4 years after the surgery so far.

 Surgery is the principal method for the treatment of solitary EMP originating in the large intestine, and we show here that laparoscopic surgery is an effective therapeutic option, thus, it may be adopted as a standard procedure for treatment of EMP.
