HistoryThis section has been translated automatically.
DefinitionThis section has been translated automatically.
Very rare (about 200 cases in world literature), autosomal dominant inherited, but also sporadically occurring, androtropic vascular malformation with multiple angiomas of the skin and various internal organs. Predominantly blind courses, very rarely fulminant or fatal forms.
The autonomy as an entity is doubted by some authors because of the clinical consistency with generalized glomangiomatosis despite different histology and etiology.
EtiopathogenesisThis section has been translated automatically.
Mutations in the TEK gene (VMCM, TEK-TIE2 gene), which is mapped on gene locus 9q21, with consecutive disruption of the receptor tyrosine kinase TIE-2.
ManifestationThis section has been translated automatically.
LocalizationThis section has been translated automatically.
On the whole integument, also on the oral mucosa (hard palate, cheek mucosa).
Clinical featuresThis section has been translated automatically.
Integument: A few or up to more than 100 differently sized, blue-black, subcutaneous or cutaneous, sharply defined papules or nodules (size 0.8-1.5 cm) of soft to rubbery (naming!) consistency. Sometimes the papules can be completely compressed. Occasional focal bleeding possible.
Oral mucosa: Angiomatous lesions are possible on the hard palate as well as in the buccal mucosa.
Extracutaneous manifestations: Frequent angiomas in the gastrointestinal tract (especially stomach, intestines) with risk of bleeding. Angiomas in the liver, spleen, gall bladder, kidney, pleura, lungs, CNS and musculature have been described (mostly asymptomatic, only detected during extensive diagnostics).
HistologyThis section has been translated automatically.
DiagnosisThis section has been translated automatically.
Differential diagnosisThis section has been translated automatically.
Complication(s)This section has been translated automatically.
TherapyThis section has been translated automatically.
No known causal therapies.
Clarification of mainly gastrointestinal organ involvement; regular monitoring and, if necessary, symptomatic surgical treatment in collaboration with surgeons and internists.
An individual case report exists on the use of "low-dose sirolimus" as an antiangiogenic principle. This includes regression of existing intestinal bleeding.
Skin lesions can be removed surgically or by laser if necessary. Good experiences have been made with cryosurgery.
