Concomitant Hodgkin’s lymphoma and gastric adenocarcinoma: a rare coincidence

Gastric adenocarcinomas may be seen together with colon, prostate, breast, liver, lung and gynecological malignancies as synchronous or metachronous cancer. However, Hodgkin’s lymphoma (HL) is rarely diagnosed with solid tumors. Herein, a 72-year-old man with both gastric adenocarcinoma and HL has been presented. Mass lesions far away from the primary tumor in cancer patients can be not only the sign of distant metastasis but also another primary malignancy. In the English literature, synchronous gastric adenocarcinoma and HL has been rarely reported, and as far as we know, this is the third case to be reported.
