A new pattern of histologic predominance and distribution of malignant diseases of the small intestine.
Taggart DP., Imrie CW.
One hundred and six patients presenting with primary malignant lesions of the small intestine during a 15 year period from 1969 to 1983 have been reviewed with respect to the histologic nature and location of the neoplasms within the small intestine. In contrast with the results of previous reports, we have found lymphoma to be the most common primary malignant condition of the small intestine. Two populations of patients with lymphomas may exist--those associated with celiac disease being confined to the proximal part of the jejunum and those arising de novo from lymphomatous tissue in the distal part of the ileum. Patients with carcinoma had the primary tumor frequently located in the distal portion of the small intestine.
