Submassive pulmonary thromboembolism as a first sign of occult adenocarcinoma

Abstract

Venous thromboembolism is one of the most common complications of cancer, which also contributesto mortality in cancer patients. Venous thromboembolism can be observed as the first manifestationof occult cancer. We present the case of a 54-year-old woman with deep vein thromboembolism andpulmonary embolism as the first signs of cancer, who was subsequently diagnosed with disseminatedadenocarcinoma, most likely originated from the pancreatico-biliary system.
