HistoryThis section has been translated automatically.

Dabska, 1969

DefinitionThis section has been translated automatically.

Extremely rare, intralymphatically growing vascular tumor of childhood of unclear dignity.

ManifestationThis section has been translated automatically.

Occurs mainly in early childhood; less frequently congenital; less frequently in older patients (Ø 30 years).

LocalizationThis section has been translated automatically.

Head, neck, neck, torso; more rarely extremities.

Clinical featuresThis section has been translated automatically.

Dermatologically uncharacteristic. Firm, red to blue-red nodular or flat tuberous swellings of the skin and subcutaneous fat tissue up to 40 cm Ø. Frequently arising in pre-existent lymphatic malformations or in lymphangiomas.

HistologyThis section has been translated automatically.

Intralymphatic proliferates located in the dermis or subcutis but also affecting internal organ systems (e.g. bone structures) consisting of grape-shaped papillae (dabskoid tufts) with a homogeneous connective tissue base (immunoreactive for collagen type IV) covered with hobnail endothelia . This results in a glomeruloid (kidney glomerula-like) aspect. Focal lymphoid cell infiltrates.

Immunohistology: Smooth muscle actin-positive pericytes are absent (suggests lymphatic genesis); endothelia express among others VEGFR-3 (marker for lymphatic endothelia) and podoplanin.

Differential diagnosisThis section has been translated automatically.

Retiform Hemangioendothelioma

Progression/forecastThis section has been translated automatically.

Dignity doubtful. After surgical removal high recurrence rate (40%); regional lymph node metastases are possible but rare, very rare distant metastases.
