Celiac Disease: Does Hyposplenism Predispose to the Development of Malignant Disease?

Splenic size and function was assessed in eight patients with celiac disease and coexisting malignancy (six had small bowel lymphoma and two gastric adenocarcinoma). The size of the spleen was reduced in four of seven patients as seen at autopsy or radionucleotide scanning. Splenic function was studied using “pitted” erythrocyte counts, platelet counts, and Howell‐Jolly bodies and was impaired in five of eight patients. Malignant disease developed in some celiacs with normal splenic size and function. Splenic function as measured by pitted erythrocyte counts was similar in the celiac patients with malignancy and appropriately matched nonmalignant celiacs. We conclude that hyposplenism in celiac disease does not influence the development of malignant disease.
