The immunologic system, immunologic deficiency disorders and lymphoid hyperplasia of the small intestine

The purpose of this paper is to review our current concept of the systems that subserve immunological functions. It concerns specifically the immunodeficiency diseases probably due to a B cell immunodeficiency. An attempt is made to classify those diseases clinically as well as roentgenologically. At last using the enteroclysis technique some examples of immunodeficiency syndromes are shown with special emphasis on developing a malignant disease.
