epithelium is a tissue composed of a layer of cells. In humans, it is one of four primary body tissues.
Epithelium lines both the outside (skin) and the inside cavities and lumen of bodies. The outermost layer of our skin is composed of dead stratified squamous epithelial cells, as are the mucous membranes lining the inside of mouths and body cavities.
Other epithelial cells line the insides of the lungs, the gastrointestinal tract, the reproductive and urinary tracts, and make up the exocrine and endocrine glands.
Functions of epithelial cells include secretion, absorption, protection, transcellular transport, sensation detection, and selective permeability. Endothelium (the inner lining of blood vessels) is a specialized form of epithelium.

Skin as well as all other organs. The circulatory system (blood vessels) have epithelial cells and all organs receive blood from these vessels. It's also found in the lumen of organs such as kidneys, stomach, large/small intestines, gallbladder, uterus, Fallopian tubes, bladder, etc.

Actually, the epithelial cell is not contained into an organ. It is covering the upper breathing system. It is contained in the ' passage' between the mouth and the throat, and also into the nose. It is used to prevent harmful bacteria from entering the lungs.

The skin is the largest organ.....and is the first one to come to my mind about epithelial cells.

Organ specificity of epithelial cells grown in tissue culture from explants obtained from various levels of the rat gut.

Epithelial cells are located in various places around the body. Most notably the skin, and make the lining of your mucous membranes like your mouth and the lining of some organs (lungs, Gastrointestinal tract, urinary tracts) try wikipedia, they might be able to help

From what I can tell, they're in many different organs, not just one. You can check wikipedia for a table of the organs, if you want:

skin: Crime scene investigation is my life. It is amazing what crimes can be solved now with epithelial cells. I certainly wouldn't strangle anyone with a rope now. I did not however realize skin is considered an organ.

Epithelia cell is the covering of internal and the external surface of the body including the lining of vessels and other small cavities.
