What is commonest morphology of gastric cancer?
Tubular adenocarcinoma is the most common histologic type of early gastric carcinoma (Figure 1).
What size is an abnormal lymph node?
In general, lymph nodes greater than 1 cm in diameter are considered to be abnormal. Supraclavicular nodes are the most worrisome for malignancy.
What size is Virchow’s node?
The VN in our case was anterior to the anterior scalene muscle, which is the normal location of the end node of the thoracic duct. For reference, an in vivo clinical image of a VN of similar size (3.0 x 2.5 cm) and location to that reported in this study has been presented by Siosaki and Souza.

What is the structure of adipose tissue?
Adipocytes are energy storing cells that contain large globules of fat known as lipid droplets surrounded by a structural network of fibers. How is adipose tissue classified? Adipose tissue is a specialized type of connective tissue that arises from the differentiation of mesenchymal stem cells into adipocytes during fetal development.
What are the traditional histologic techniques for adipose tissue analysis?
Traditional histologic techniques for adipose tissue analysis have included electron microscopy (transmission and scanning) and freeze fracturing. Many laboratories analyze adipose tissue with light microscopy (LM) techniques such as immunohistochemistry and in situ hybridization (Cinti, Zingaretti, Cancello, Ceresi, & Ferrara, 2001).
What is visceral white adipose tissue?
Human fat is predominantly represented by white adipose tissue, which is organized in subcutaneous and visceral adipose tissue. Visceral white adipose tissue consists of gonadal fat deposits, epicardial adipose tissue, retroperitoneal, mesenteric, omental fat depots, and perirenal adipose tissue (PRAT) [ 5, 6 ].
What is the difference between white and brown adipose tissue?
Unlike white adipose tissue, brown adipose tissue, also known as brown fat, is mostly present during fetal life and in infants. In newborns, brown adipose tissue is mainly located on the back, along the upper half of the spine, in between the shoulders, and surrounding the kidneys. With age, the amount of brown fat decreases progressively.
