Hamartoma
A hamartoma is a benign (noncancerous) tumor-like growth
consisting of a disorganized mixture of cells and tissues
normally found in the area of body where the growth occurs.
- For example, hamartoma of lung contains cartilage, blood vessels,
bronchial type of structures and lymphoid
tissues. - It is a focal development malformation that resembles a neoplasm
in the tissue of origin. - But, it is not a neoplasm because it grows at the same rate as the
surrounding tissues unlike neoplasm whose
growth exceeds the growth of surrounding tissue.
Choristoma - Choristoma is the ectopic rest of normal tissue, i.e., the normal
tissue is present at a different anatomical site of the
body. - For example, presence of pancreatic tissue in mucosa of small
intestine. - Normally arranged tissue at a different anatomical site (ectopic
site) → Choristoma. - Abnormally arranged tissue present at normal
site -Hamartoma
