Mr. G.S., a 48-year-old business consultant with an unremarkable past medical history save for obesity (122 kg/180 cm), migraines and “lactose intolerance,” returned in the spring from a 2-week trip to Europe and Russia. After landing in Toronto, he noted some irritation and a cramp-like feeling in his left leg. He went to a walk-in-clinic, was diagnosed with “phlebitis” and given anti-inflammatory agents. He took them but had no relief, so after arriving at home, he went to the local emergency room, where he also complained of dry cough. Mr. G.S. underwent venous doppler and CT chest scans. These were negative for DVT and pulmonary embolism (PE), and he was treated with a course of antibiotics and anti-inflammatories for leg pain.
The cough continued to progress, to the extent that at times he coughed up bile. He denied phlegm or hemoptysis, though. During the next couple of weeks, he experienced intermittent fever and night sweats. He had occasional symptoms of heartburn and reflux. He denied symptoms of abnormal bowel movements, bleeding per rectum, melena, joint pain or joint stiffness. He’d been working on weight loss over the past year and claimed to have lost 13½ kg in the past 6 months, through various diets. There was no history of sexual contact overseas, genito-urinary symptoms or urethral discharge.
He took pantoprazole 40 mg a day, clarithromycin and budesonide/formoterol. He was a non-smoker and denied alcohol use. His work involved frequent travel to different continents.
Physical exam revealed a BP of 146/84 mm Hg and regular rhythm. There was no cervical or axillary lymphadenopathy noted. Heart sounds were distant but normal. Lungs were clear. Abdomen was soft and obese. No organomegaly was noted. There was no calf tenderness and Homan’s sign was negative. There was, however, chronic induration of both lower legs and ankles and a slightly tender cord-like structure on the medial aspect of the left knee in the left saphenous and popliteal veins. There were no skin lesions or lesions compatible with erythema nodosum.
A chest x-ray was unremarkable. ESR was normal at 14, as was his CBC and electrolytes.
The possibilities of viral syndrome, sarcodosis, TB (in view of travel, dry cough, fever, night sweats) and superficial phlebitis (DVT was ruled out) were considered, but a Mantoux test was negative.
Over the next 4 weeks, his symptoms continued to progress rapidly and he began experiencing ongoing fever and night sweats with a decreased appetite. In just one month, he developed superficial phlebitis involving the right leg and left arm, and he also developed DVT, PE and thrombophlebitis of the left internal jugular vein.
What’s wrong with Mr. G.S?

Migratory thrombophlebitis
The clinical features and findings on physical examination of Mr. G.S. are highly suspicious for migratory thrombophlebitis, or thrombophlebitis migrans, also known as Trousseau sign of malignancy or Trousseau syndrome, to differentiate this from Trousseau sign of latent tetany. Some malignancies, especially adenocarcinomas of the pancreas or lung, are associated with hypercoagulability and in such patients with malignancy-associated hypercoagulable states, the blood may spontaneously form clots in the portal vessels, veins of the extremities, or the superficial veins anywhere on the body. These clots present as visibly swollen and tender cord-like structures and present as intermittent pain in the affected areas.
This pathological phenomenon of clots forming, resolving and then appearing again elsewhere in the body is known as thrombophlebitis migrans or migratory throbophlebitis and was first described by Armand Trousseau in the 1860s, who later found this sign in himself and was diagnosed with gastric cancer.
The possibility of a neoplastic process, like an adenocarcinoma, was entertained at this time and Mr. G.S. underwent a CT scan of the abdomen. This showed an enlarged pancreas with ill-defined edges and enlarged lymph nodes in the abdomen and in the porta hepatis, as well as the presence of ascites. He underwent laparoscopic biopsy of these lymph nodes that confirmed metastatic poorly differentiated adenocarcinoma, which was believed to be of pancreatic origin.
The patient was transferred to the regional cancer centre for further assessment and management but was felt to have a poor prognosis. He was transferred back to the local hospital for end-of-life care.
