What are papillary cells?
Papillary renal cell carcinoma, or PRCC, is a type of kidney cancer. The kidneys work by removing waste products from the blood. Papillary renal cell carcinoma is a cancer of the tubes that filter those waste products from the blood. There are two types of papillary renal cell carcinoma.
What is the survival rate for adenocarcinoma?
Survival rates can give you an idea of what percentage of people with the same type and stage of cancer are still alive a certain amount of time (usually 5 years) after they were diagnosed….5-year relative survival rates for small intestine cancer.

| All SEER stages combined | 68% |
What is anaplastic cell?

In some adenomas (benign glandular tumors), a change can cause the cells to become less differentiated, or to show anaplasia. In this case, these benign cells can actually become a malignant adenocarcinoma. Most often, they do not.
What is the papillary layer made of?
collagen fibers
Papillary dermis: The papillary layer is the top layer of your dermis. It’s much thinner than the reticular dermis. It consists of collagen fibers, fibroblast cells, fat cells, blood vessels (capillary loops), nerve fibers, touch receptors (Meissner corpuscles) and cells that fight bacteria (phagocytes).
What tissue is the papillary layer made of?
loose connective tissue
The papillary dermis is composed of loose connective tissue (LCT) and is highly vascular. The reticular dermis shows thick collagen bundles and forms the bulk of the dermal layer.
