Nikon MicroscopyU: Human Pathology Digital Image Gallery - Oat Cell Carcinoma Oat cell carcinoma, also known as small cell carcinoma, is a type of lung cancer that is characterized by small, oat-shaped malignant cells. Oat cell carcinoma is extremely aggressive and, in the majority of cases, by the time a diagnosis is made, the cancer has already metastasized to other parts of the body. Due to the high metastatic rate of oat cell carcinomas, the cancer is rarely well suited for treatment by surgery, though in some limited stage cases of the cancer in which the lymph nodes are not involved it may be recommended. www.microscopyu.com /galleries/pathology/oatcellcarcinoma.html   (577 words)

Carcinoma - Wikipedia, the free encyclopedia Carcinoma in situ (CIS) is a pre-malignant condition, in which cytological signs of malignancy are present, but there is no histological evidence of invasion through the epithelial basement membrane. Sometimes a tumour is referred to by the presumptive organ of the primary (eg carcinoma of the prostate) or the putative cell of origin (hepatocellular carcinoma, renal cell carcinoma). This is a common in the lung forming 30-40% of all lung carcinomas, found peripherally, arising from goblet cells or type II pneumocytes. en.wikipedia.org /wiki/Carcinoma   (496 words)

Merkel Cell Carcinoma:   (Site not responding. Last check: 2007-10-20) Merkel cell carcinoma, also called neuroendocrine cancer of the skin, is a rare type of disease in which malignant (cancer) cells are found on or just beneath the skin and in hair follicles.

Squamous cell carcinoma - Wikipedia, the free encyclopedia In medicine, squamous cell carcinoma is a form of cancer of the carcinoma type that may occur in many different organs, including the skin, mouth, esophagus, lungs, and cervix. Squamous cell carcinomas account for about 20% of non-melanoma skin cancers, (with basal cell carcinomas accounting for about 80%), but are clinically more significant because of their ability to metastasize. Squamous cell carcinoma is usually developed in the epithelial layer of the skin and sometimes in various mucous membranes of the body. en.wikipedia.org /wiki/Squamous_cell_carcinoma   (333 words)

Skin cancer symptoms, signs, prevention, and treatment and information on the types of skin cancer on MedicineNet.com Basal cell carcinoma is the most common form of skin cancer and accounts for more than 90 percent of all skin cancer in the U.S. These cancers almost never spread (metastasize) to other parts of the body. A basal cell carcinoma usually begins as a small, dome-shaped bump and is often covered by small, superficial blood vessels called telangiectases. Mohs micrographic surgery is preferred for large basal cell carcinomas, those that recur after previous treatment, or lesions affecting parts of the body where experience shows that recurrence is common after treatment by other methods. www.medicinenet.com /skin_cancer/article.htm   (1339 words)

Adrenocortical Carcinoma Adrenocortical carcinoma is a rare tumor afflicting only one to two persons per one million population.
