CUTANEOUS METASTASES

CUTANEOUS METASTASES

Metastasis to the skin is an uncommon presentation of internal malignancy. Cutaneous metastases are far more likely to be seen in a patient with a diagnosis of previously metastatic disease. The frequency of cutaneous metastasis is dependent on the primary tumor. Almost all types of internal malignancy have been reported to metastasize to the skin; however, a few types of cancers account for the bulk of cutaneous metastases. The distribution of the metastases is also dependent on the original tumor. The most common form of skin metastasis is from an underlying, previously metastatic melanoma.

Renal Pelvis, Ureter, And Bladder

Renal Pelvis

The entire urine collecting system is lined by a sheet of transitional epithelium known as urothelium. In the renal pelvis, the urothelial cells are two or three layers thick. The most superﬁcial cells are larger than the others and send projections down over the lateral surfaces of the cells beneath them, sometimes having an umbrella-like appearance. These “umbrella cells” have abundant eosinophilic cytoplasm and may be binucleate. Underneath the umbrella cells are smaller intermediate cells and basal cells.

What Does The Spinal Cord Do?

What Does The Spinal Cord Do?

The spinal cord actually is part of the brain and plays a major role. Scientists have known for the past 100 years or so that the spinal cord is actually part of the brain. According to Melillo, while the brain has grey matter on the outside (protected by the skull) and protected white matter on the inside, the spinal cord is the reverse: the grey matter is inside the spinal cord and the white matter is outside.

These joints include those between the tarsal bones, the metatarsals and the phalanges. They are all synovial and have shapes related to their movements.

Gastrointestinal Hormones

Gastrointestinal Hormones

The epithelium of the gastrointestinal tract contains multiple cell types, including specialized cells termed enteroendocrine cells that number less than 1% of the cell population and yet form the largest endocrine system of the body. Enteroendocrine cells synthesize, store, and release chemical transmitters that are involved in gastrointestinal motility, secretion, and absorption and in regulation of appetite. These transmitters are predominantly small polypeptides that are also found in the enteric nervous system and the central nervous system. There are more than 30 gut peptide hormone genes identified, which express more than 100 bioactive peptides. They are grouped into “families” according to their primary structure. In this section, the pancreatic polypeptide family will be discussed.

1. This technique enables revascularization with a similar configuration as that in a sternotomy technique, using left internal thoracic artery (LITA) harvesting and hand-sewn proximal and distal anastomoses under direct visualization.1,2 Complete revascularization is achieved in 95% of cases,1 allowing access to the anterior, lateral, and inferior walls of the heart, with or without the use of pump assistance.
