A teratoma is a tumor that is made up of many different types of tissue. BAC clones were selected according to their genomic location using the UCSC Genome Browser http://www.genome.ucsc.edu/ and labeled by nick translation according to manufacturer's protocol (Vysis/Abbott). A 1.7 × 1.0 × 0.6 cm lobulated, light gray to tan, fragment of soft tissue was received for examination. One general danger of hamartomas is that they may impinge into blood vessels, resulting in a risk of serious bleeding. All of those conditions are types of different cell growth disturbances. For example, when located on the skin, especially on the face or neck, they can be very disfiguring.
