Additionally, the definition of hamartoma versus benign neoplasm is often unclear, since both lesions can be clonal. Lesions such as adenomas, developmental cysts, hemangiomas, lymphangiomas, and rhabdomyomas within the kidneys, lungs, or pancreas are interpreted by some experts as hamartomas while others consider them true neoplasms.

Recognition of this finding is important to prevent the erroneous belief that the region of sparing is itself a mass. Neoplasias, on the other hand, consist of ABNORMAL cells because they have uncontrolled or unregulated growth.

Hamartoma - Disorganized overgrowth of tissues in their normal location - Peutz-Jeghers polyps. Supratentorial and Infratentorial Structures. For example, Andrade and Raikwar mentioned a case of congenital benign teratoma of the tongue with bifid tip, ankyloglossia and polydactyly. Such masses may include simple hyperplasia, hamartoma, choristoma, teratoma, benign or malignant neoplasms. The distinguishing features of hamartomatous lesions are not certain, and often these non-neoplastic masses are indiscreetly denoted as neoplasms without weighing their pathology or biological behaviour.
