EtiopathogenesisThis section has been translated automatically.
Infectious disease caused by HHV-8; in a Finnish (!) population with familial classic KS a mutation in the STAT4 gene (see STAT below) was detected.
ManifestationThis section has been translated automatically.
m:f = 18:1; first manifestation > 75 years (in contrast to the epidemic KS; here the age of onset of the disease is 30 years) In larger collectives, an average age of 75.8 years was given for the first manifestation of the disease.
LocalizationThis section has been translated automatically.
>90% of lesions are found on the lower extremity, especially on the lower legs. Occasionally also on the upper extremity and on the face
Clinical featuresThis section has been translated automatically.
Multiple, uni- or bilaterally occurring, initially mostly painless red or red-blue spots, which develop over the course of months/years into red flat plaques and later into red or blue-red nodules. Mostly occurring in combination with lymphedema. Confluence to larger (>10.0cm) plaques. Erosions, excoriations and ulcers possible. Infestation of internal organs often goes unnoticed.
HistologyThis section has been translated automatically.
TherapyThis section has been translated automatically.
Several therapy modalities are described as successful.
In the case of localized infestation, surgery can be performed (excision, ablative laser, curettage). At the same time a compression therapy of the US is recommended.
Chemotherapy is recommended for disseminated infestation.
Progression/forecastThis section has been translated automatically.
Moderately good forecast with decades of progress. Metastasis in lung and lymph nodes possible.
