ham·ar·to·ma

(ham'ahr-tō'mă),
A focal malformation that resembles a neoplasm, grossly and even microscopically, but results from faulty development in an organ; composed of an abnormal mixture of tissue elements, or an abnormal proportion of a single element, normally present in that site, which develop and grow at virtually the same rate as normal components, and are not likely to result in compression of adjacent tissue (in contrast to a neoplasm).

hamartoma

A tumor-like, non-neoplastic disordered proliferation of mature tissues that are native to a site of origin–eg, exostoses, nevi and soft tissue hamartomas; although most hamartomas are benign, some histologic subtypes–eg, neuromuscular hamartoma, may proliferate aggressively.

(ham'ahr-tō'mă)
A focal malformation that resembles a neoplasm, grossly and even microscopically, but that results from faulty development, with a disproportion or abnormal mixture of tissue elements normally present at the site; develops and grows at virtually the same rate as normal tissue and is not likely to compress or invade adjacent structures (in contrast to a neoplasm).

hamartoma

A rare BENIGN tumour of mixed normal cells that can affect any organ and that contains tissues normal to the organ. A lung hamartoma containing bronchial lining cells, connective tissue and cartilage, may cause obstruction of a BRONCHUS. As a rule, hamartomas do little harm.
