Definition of adenocarinoma
Cancer that begins in the epithelial cells, which line certain internal organs and have glandular (secretory) properties. Some types of adenocarcinomas include cancers of the breast, thyroid, colon, stomach, pancreas, and prostate, as well as certain types of lung cancer.

Classification of carcinoma
Carcinoma, like all neoplasia, is classified by its histopathological appearance. Adenocarcinoma and squamous cell carcinoma, two common descriptive terms for tumors, reflect the fact that these cells may have glandular or squamous cell appearances respectively. Severely anaplastic tumors might be so undifferentiated that they do not have a distinct histological appearance (undifferentiated carcinoma).
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).
Angie I think it is just a slight split in terminology for classification of type of cells. You have to be a pathologist to really understand the concrete differences in these cells. Shape, size, origin, pathway, sometimes even color . Hope this helps as this was not one of my strong studies. LOL marty
