The meaning of the hamartoma

Se ha propuesto una clasificacion de los (HH) basada en datos topograficos , estas lesiones pueden ser asintomaticas o pueden ir asociadas con ciertos problemas, entre ellos la pubertad precoz; no obstante estos avances y estudios, poco se conoce acerca de la historia natural de los Hamartomas
We describe a case of adenocarcinoma within a retrorectal cystic hamartoma
, initially manifesting in a 54-year-old woman and recurring over a 5-year period.
Cysts and bile duct hamartomas
are hypointense in T1 and hyperintense in T2; they are differentiated by a thin ring of gadolinium enhancement, hemangiomas are more common in women, they are hypointense in T1 and moderately hyperintense in T2, with a centripetal enhancement in the arterial phase.
A cortical tuber in the right frontal lobe of the brain and a subependymal hamartoma
in the right lateral ventricle were detected (Fig.

Primary Diagnostic Criteria of Tuberous Sclerosis * Cortical tubers * Facial angiofibromas * Retinal hamartomas
* Subependymal glial nodules * Ungual fibromas Modified from Gomez and Roach, et al[23,24]
Surgical removal of hamartomas
and other benign brain tumors is often difficult or impossible, and doctors usually choose not to operate when the only serious complication of these tumors is precocious puberty.
