Areolar Tissue: Slide 4: Areolar Tissue Found underlying most epithelial tissue, forms the papillary region of the dermis and a layer called the Lamina propria of the Digestive Tract found just underlying the epithelium. In this slide, the areolar tissue is part of one of the serous membrane.
1 Type of tissue from which the cancer evolved, including carcinomas and sarcomas. 2  Carcinoma is a cancer that begins in the skin or in tissues that line or cover internal organs. 3  Sarcoma is a cancer of the bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue.

Carcinomas are cancers that arise in the epithelium (the layer of cells covering the body's surface and lining the internal organs and various glands). Ninety percent of human cancers fall into this category. Carcinomas can be subdivided into two types: adenocarcinomas and squamous cell carcinomas.
