  • cancers
  • These conditions are characterized by the growth of multiple hamartomas and an increased risk of developing certain cancers, particularly breast cancer, thyroid cancer, and cancer of the uterine lining (endometrial cancer). (nih.gov)
  • Cowden's
  • In patients with Cowden's syndrome , retroperitoneal fibrosis, mediastinal fibrosis, sclerosing cholangitis, Riedel's thyroiditis, and inflammatory pseudotumor of the orbit can all manifest, either alone or in combination. (thefreedictionary.com)
  • disorder
  • Bannayan-Riley-Ruvalcaba syndrome is a congenital disorder characterised by hamartomatous intestinal polyposis, macrocephaly, lipomatosis, hemangiomatosis and glans penis macules. (wikipedia.org)
  • blood vessels
  • One general danger of hamartomas is that they may impinge into blood vessels, resulting in a risk of serious bleeding. (wikipedia.org)
  • Evidence suggests that this enzyme also helps control cell movement (migration), the sticking (adhesion) of cells to surrounding tissues, and the formation of new blood vessels (angiogenesis). (nih.gov)
  • occur
  • Hamartomas occur in many different parts of the body, and are most often asymptomatic incidentalomas (undetected until they are found incidentally on an imaging study obtained for another reason). (wikipedia.org)
  • citation needed] The most common hamartomas occur in the lungs. (wikipedia.org)
  • diagnose
  • This case suggests that it is critical for clinicians to recognize the phenotypic features associated with these syndromes to accurately diagnose them and provide preventive care. (e-crt.org)
  • diagnosis
  • An X-ray will often not provide a definitive diagnosis, and even a CT scan may be insufficient if the hamartoma lacks the typical cartilage and fat cells. (wikipedia.org)
  • often
  • Some lung hamartomas can compress surrounding lung tissue to a degree, but this is generally not debilitating and is often asymptomatic, especially for the more common peripheral growths. (wikipedia.org)
  • Many causes of the epilepsy have been theorized, with EEG often finding the hamartoma itself as the source of electrical activity, or epileptogenic focus. (wikipedia.org)
  • skin
  • The two can be differentiated as follows: a hamartoma is an excess of normal tissue in a normal situation (e.g., a birthmark on the skin), while a choristoma is an excess of tissue in an abnormal situation (e.g., pancreatic tissue in the duodenum). (wikipedia.org)
  • sometimes
  • They can be worrisome, especially if situated deep in the lung, as it is sometimes difficult to make the important distinction between a hamartoma and a lung malignancy. (wikipedia.org)
  • found
  • Moreover, even though hamartomas show a benign histology, there is a risk of some rare but life-threatening clinical issues such as those found in neurofibromatosis type I and tuberous sclerosis. (wikipedia.org)
  • risk
  • One general danger of hamartomas is that they may impinge into blood vessels, resulting in a risk of serious bleeding. (wikipedia.org)
