A mass mimicking primary pancreatic malignancy

Abstract

Colorectal cancer ranks third among all cancers in terms of prevalence. It is the second most common cause of death overall. The patterns of spread are lymphatic, hematogenous, and direct invasion. Lymph node involvement is a prognostic factor and has a strong correlation with survival and disease free interval. Regional lymph nodes are frequently the first structures to get affected. Metastatic disease (stage IV) is defined as the spread of disease to lymph nodes other than regional ones. Because of this, the type of treatment that is administered and the patient's survival rate are both affected when the cancer spreads to non-regional lymph nodes. In this particular instance, we report a patient who had results that were consistent with having a pancreatic tumor. Nevertheless, with the aid of endoscopic ultrasonography, we determined that the patient had metastatic colon cancer. And the patient's trajectory takes a dramatic turn for the worse, shifting from resectable pancreatic cancer to metastatic colon cancer.
