The proximal jejunum, containing four separate amyloid tumors, was resected from a chronically constipated 71‐year old male exhibiting 1gG lambda monoclonal gammopathy. Amyloid was deposited in the jejunal wall, mesentery and regional lymph nodes, but was not seen in gastric and rectal biopsy samples. Two years after surgery, the patient is well, but the monoclonal gammopathy persists. Acta Pathol. Jpn. 32: 207∼211, 1989.
