• intravascular adenomyomatosis
  14 October 2013

  Intravenous leiomyomatosis (IVL) is a rare smooth-muscle proliferation that is of special interest because of its quasi-malignant behavior.
  Intravascular leiomyomatosis (IVL) is characterized by the presence of smooth muscle in venous and lymphatic spaces within the myometrium.
  Although the intravascular component usually consists solely of typical smooth muscle or variants of smooth muscle differentiation, some cases have been reported in which the intravascular component also included (...)

• atheroma
  26 September 2012

  WKP
  Definition: In pathology, an atheroma (from ἀθήρωμα (athērōma), “tumor full gruel-like matter”) is an accumulation and swelling in artery walls made up of (mostly) macrophage cells, or debris, and containing lipids (cholesterol and fatty acids), calcium and a variable amount of fibrous connective tissue.
  Atheroma causes atherosclerosis, which is one of the three subtypes of arteriosclerosis (which are atherosclerosis, Monckeberg’s arteriosclerosis and arteriolosclerosis).

• lobular capillary hemangioma
  6 July 2012

  pyogenic granuloma
  Definition: Lobular capillary hemangioma (LCH) is a specific entity among vascular lesions of the head and neck that may be diagnosed loosely as “pyogenic granuloma”. In contrast to granulation polyps and other reactive conditions, LCH is regarded as likely a benign vascular neoplasm.
  Lobular capillary hemangioma is a lesional pattern that can be observed in several vascular tumors or vascular malformations (vascular dysplasias). Lobular capillary hemangioma is a common (...)

• atypical hemolytic uremic syndrome
  13 January 2012

  Atypical hemolytic uremic syndrome (aHUS) is a disease characterized by excessive complement activation in the microvasculature.
  In both the familial and sporadic forms, inherited and acquired abnormalities affecting components of the alternative complement pathway are found in ∼ 60% of patients.
  These include mutations in the genes encoding both complement regulators (factor H, factor I, membrane cofactor protein, and thrombomodulin) and activators (factors B and C3) and autoantibodies (...)

• abdominal aortic aneurysm
  14 November 2011

  Abdominal aortic aneurysm (AAA) is a common cause of morbidity and mortality and has a significant heritability.
  Pathology
  Variant rs1466535, located within intron 1 of low-density-lipoprotein receptor-related protein 1 (LRP1), might alter a SREBP-1 binding site and influence enhancer activity at the locus. This variant has a possible functional role in LRP1 expression. (#22055160#)
