Squamous cell carcinoma or squamous cell cancer (SCC or SqCC) is a cancer of a kind of epithelial cell, the squamous cell. These cells are the main part of the epidermis of the skin, and this cancer is one of the major forms of skin cancer. However, squamous cells also occur in the lining of the digestive tract, lungs, and other areas of the body, and SCC occurs as a form of cancer in diverse tissues, including the lips, mouth, esophagus, urinary bladder, prostate, lung, vagina, and cervix, among others. Despite sharing the name squamous cell carcinoma, the SCCs of different body sites can show tremendous differences in their presenting symptoms, natural history, prognosis, and response to treatment.

Micrograph of Renal Cell Carcinoma (RCC). Renal cell carcinoma is a kidney cancer that originates in the lining of the proximal convoluted tubule, a part of the very small tubes in the kidney that transport waste molecules from the blood to the urine. RCC is the most common type of kidney cancer in adults, responsible for approximately 90–95% of cases. Initial treatment is most commonly either partial or complete removal of the affected kidney(s). Where the cancer has not metastasised (spread to other organs) or burrowed deeper into the tissues of the kidney, the 5-year survival rate is 65–90%, but this is lowered considerably when the cancer has spread.

WHO grade I meningioma- Brain tumours are graded from 1 - 4, according to what they look like under the microscope as well as their behaviour, such as the speed at which they are growing. Meningiomas can be graded 1, 2 or 3. Grade 1 Meningioma – the most common type, slow growing and less likely to return after treatment

Micrograph of acute myeloid leukemia (AML), also known as acute myelogenous leukemia or acute nonlymphocytic leukemia (ANLL), is a cancer of the myeloid line of blood cells, characterized by the rapid growth of abnormal white blood cells that accumulate in the bone marrow and interfere with the production of normal blood cells. AML is the most common acute leukemia affecting adults, and its incidence increases with age.

In the urinary tract there is a type of epithelium, the transitional epithelium or urothelium, which is exclusive to this region of the body. It is an epithelium with a stratified appearance, that is, whose cells are arranged in several layers from the base to the light. Above the basal layer, a variable number of cell layers are located depending on the state of distension of the organ, which can be very well evidenced in the urinary bladder. The image pertains to an empty bladder and shows 6 to 7 layers of nuclei, which are reduced to 2-3 in a full bladder. Finally, it is also characteristic of the transitional epithelium that the superficial cells and, sometimes, also in the intermediate layers, are binucleated or show very large nuclei, corresponding to polyploid nuclei.
