A case of lymphocytic lymphoma of the small intestine was associated with cryoglobulinemia and amyloidosis. The neoplastic lymphoid cell demonstrated surface IgG membrane markers by immunofluorescence and immunoelectron microscopy. The cryoglobulins were characterized as monoclonal IgG3 proteins with lambda light chains. Amyloidosis of the small intestine(More)
A case of multiple myeloma producing IgD-M component with light chains of lambda type is reported. It involved the skeleton and was complicated by compression of the spinal cord and massive extension to the pleura. The urine contained lambda Bence Jones protein.

The villous component of nine colonic polyps (three pure villous adenoma and six mixed adenomatous and villous adenomas) was studied by light and electron microscopy. Normal colonic mucosa was used for control. The predominant cell was an undifferentiated epithelial cell resembling those of the base of the crypts of normal colonic mucosa. A minority of(More)
