Trousseau’s syndrome is classically seen with:
**Core Concept**
Trousseau's syndrome, also known as migratory thrombophlebitis, is a condition characterized by recurrent, migratory episodes of venous thrombosis. It is often associated with an underlying malignancy or other systemic disease.
**Why the Correct Answer is Right**
The correct answer is associated with Trousseau's syndrome because it is a known complication of malignancy, particularly pancreatic cancer. The exact mechanism is not fully understood, but it is thought to be related to the release of pro-coagulant substances by the tumor, leading to a hypercoagulable state. This can result in the formation of blood clots in the veins, which can be migratory and recurrent.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because, while it is a known cause of thrombosis, it is not specifically associated with Trousseau's syndrome.
**Option B:** This option is incorrect because it is not a recognized cause of migratory thrombophlebitis.
**Option C:** This option is incorrect because, although it can cause thrombosis, it is not specifically linked to Trousseau's syndrome.
**Clinical Pearl / High-Yield Fact**
Trousseau's syndrome is an important clinical correlation to remember, as it can be a presenting feature of an underlying malignancy. A high index of suspicion is necessary, especially in patients with recurrent episodes of venous thrombosis.
**Correct Answer: D. Pancreatic cancer**
