HamartomQ85.91
Synonym(s)
DefinitionThis section has been translated automatically.
Congenital or later manifesting malformations that develop as a result of abnormal compositions of structures normally found in a tissue (e.g., nevus sebaceus; e.g., cartilage proliferates in the bronchial wall). Unlike neoplasia, their growth is not autonomous but parallels the growth of the surrounding tissue.
The term " nevus", as a hamartoma of the skin is used only in dermatological language.
Hamartomas develop particularly frequently as malformations of blood vessels and in fatty tissue.
The term hamartoma is to be distinguished from the term choristoma. This term is used to describe a dysontogenetic tumor that develops as a result of tumor-like proliferation of scattered, non-local tissue (choristoma).
