Final answer:
Trousseau's syndrome is referred to as tender migratory thrombophlebitis and is associated with hypercoagulability related to an underlying malignancy such as pancreatic adenocarcinoma.
Step-by-step explanation:
The oncologist's note of a positive Trousseau's syndrome in a patient diagnosed with pancreatic adenocarcinoma refers to D) Tender migratory thrombophlebitis. Trousseau's syndrome, also known as Trousseau's sign of malignancy, is a medical condition associated with hypercoagulability in the presence of an active cancer. It involves the spontaneous formation of blood clots in the superficial or deep veins, which can be migratory and recur in different locations. This condition often precedes the diagnosis of malignancies such as pancreatic cancer and can sometimes be the initial manifestation of an otherwise occult cancer.
