HistoryThis section has been translated automatically.

Calonje, 1994

DefinitionThis section has been translated automatically.

Extremely rare, intralymphatic growing vascular tumor. To what extent this tumor type is clearly different from the hemangioendothelioma of the Dabska type (this type primarily affects children) is currently still controversial.

ManifestationThis section has been translated automatically.

All age groups from the 1st-8th decade of life can be affected. Women >Men. In a smaller series (n=8), the mean age was 40 years (range: 13-69 years) (Lao IW et al. 2015).

LocalizationThis section has been translated automatically.

Lower and upper extremties; trunk (also genitals) and scalp. One case occurred in chronic lymphedema. Another case occurred after radiotherapy for carcinoma of the cervix (Calonje E et al 1994) . But also internal organs such as the skeletal system and the spleen can be primarily affected (Lao IW et al. 2015)

Clinical featuresThis section has been translated automatically.

Not specific. See below Hemangioendothelioma, Dabska type. The vascular tumor manifests as a slowly growing, exophytic, nodular or plaque-like, bluish translucent or skin-colored, elevation. Pain is reported in isolated cases (Zhang G et al. 2010).

HistologyThis section has been translated automatically.

Striking morphological features are the presence of long, branched blood vessels arranged in a reticular pattern. The vascular spaces are lined by monomorphic Hobnail endothelial cells. Characteristic is a duet lymphocytic infiltrate , as well as the focal appearance of papillary structures which are also present in endovascular or intralymphatic papillary angioendothelioma(Dabska tumor).

In immunohistochemistry, the cases consistently show positivity for endothelial markers, including CD31, human coagulation factor VIII, CD34.

Differential diagnosisThis section has been translated automatically.

Progression/forecastThis section has been translated automatically.

Retiform hemangioendothelioma proves to be a low-grade neoplasm. Postoperative recurrences are common due to the frequent multicentric growth (extent of the tumor is underestimated). The metastasis rate is low. Tumor-related deaths do not occur (Calonje E et al. 1994).
