Definition of sebaceoma


A rare, benign (not cancer) tumor that forms in an oil gland in the skin. Most sebaceomas appear as yellow, orange, or skin-colored bumps that occur on the head or neck. They tend to grow slowly and are painless. Sebaceomas may be found in people with a rare, inherited condition called Muir-Torre syndrome (MTS). People with MTS have an increased risk of developing several types of cancer. Sebaceomas most often occur in older adults. Also called sebaceous epithelioma.
