D44.4: Neoplasm of uncertain or unknown behaviour: Craniopharyngeal duct

When there is abnormal growth of tissue, then this is also referred to as a tumor. The tissue in the body is made up of cells. A tumor disorder involves the cells multiplying more than normal. This results in abnormal or excess tissue forming. A tumor can be benign or malignant.

You have a duct in your head that is affected by the tumor. While a human is developing, the pituitary gland forms in the throat. While a human is developing, the pituitary gland then travels up to the brain. This means that remnants of the pituitary gland can be left behind. These remnants can then divide uncontrollably. The pituitary gland is a gland in the brain. Many messenger substances are created for the body in this gland. These messenger substances influence growth, metabolism and sex hormones, for example.
