Dysplasia - Definition

Ask a question


Dysplasia is an abnormal development of certain organs present at birth which causes defects or deformations. Some dysplasias are compatible with life, others are not, leading to death at birth or sometimes before birth. Dysplasia causes malfunctions of the body, and can sometimes be life threatening. Numerous forms of dysplasia exist. For example, bronchopulmonary dysplasia is found in premature infants whose lungs have not reached the end of their maturation requiring appropriate care from birth. The term dysplasia is also used in another context: it is a modification of tissue notably occurring in some precancerous stages.
