title: Waldenström's disease of the jejunum.
abstract: A case of Waldenströms macroglobulinaemia with characteristic clinical features was investigated in life and at autopsy. Using immunochemical and immunohistochemical methods it was confirmed that the abnormal clone of cells producing IgM formed a solitary tumour in the jejunum causing partial obstruction. Resection of the tumour led to an improvement in the clinical condition and biochemical measurements.
