Henoch-Schonlein Purpura associated with Adenocarcinomas in Stomach and Colon / 대한신장학회잡지

ABSTRACT

There are a few reports about coexistence of Henoch-Schonlein purpura (HSP) and a variety of malignancy in adults. The accompanying malignancies, in order of frequency, were hematologic malignancy, lung cancer and prostate cancer. Gastrointestinal tract (GIT) cancer associated with HSP was rarely reported which includes 2 cases of stomach cancer, 1 case of small bowel cancer and 1 case of esophageal cancer. Malignancy is proposed to be a triggering factor in the development of HSP, however pathogenesis of HSP associated with malignancy remains obscure. Here, we report 2 cases of HSP associated with malignancy in GIT. One is an adenocarcinoma of the colon and the other is a stomach adenocarcinoma with signet ring cell component.
