Virchow Node and Troisier Sign

•

It is named after Rudolf Virchow (1821-1902), the German pathologist who first described the gland and its association with gastric cancer in 1848.

The French pathologist Charles Emile Troisier noted in 1889 that other abdominal cancers, too, could spread to the node.

•
It is quite significant because, it is also called a sentinel node or a signal node as in carcinomas its presence strongly indicates the abdominal (especially, gastric) cause of the malignancy.

It becomes hard which is quite palpable, and this is called Troisier's sign.

VALUE of ARFI and TE in HBV and HCV LIVER FIBROSIS

Abstract

Our aim was to compare liver stiffness (LS) measurements by means of acoustic radiation force impulse (ARFI) elastography and transient elastography (TE) in patients with chronic hepatitis B and C, according to the severity of fibrosis. We also compared the correlation strength of ARFI and TE measurements with liver fibrosis. We included 53 patients with hepatitis B and 107 with hepatitis C in which liver biopsy, ARFI and TE measurements were performed in the same session. The mean LS values measured with ARFI were similar in patients with chronic hepatitis B and C and depended on the stage of fibrosis. The correlation strength of LS measurements by ARFI and by TE with fibrosis was similar in chronic hepatitis B and C patients. In conclusion, for the same stage of fibrosis, the mean LS values by ARFI were similar in patients with chronic hepatitis B and C. ARFI had similar predictive value with TE in both chronic viral hepatitis.
