Hamartoma

Hamartoma refers to a tumor-like deformity caused by the incorrect combination and arrangement of normal tissues in an organ during development. Hamartomas are not real tumors. The tumors grow slowly, and the growth and growth of random bodies increase, but they can stop to a certain extent. They are coordinated with the body and rarely malignant. There are also a few scholars who believe that hamartomas are true tumors (such as renal vascular smooth muscle lipoma), rather than "abnormal combinations of normal tissues", and should be classified as mesenchymal tumors.
