Type : Other, mainly phenotypes with suspected mendelian basis;
Alternative titles and symbols : Tufted angioma;
Description : Tufted angioma is a rare benign vascular lesion that predominantly affects children
under 5 years of age but may occur in adulthood. Some cases of tufted angioma have
been reported in the mother during pregnancy, whereas in other cases the tufted angioma
may be congenital. The lesions occur predominantly on the neck, shoulders, and trunk
and appear histologically in a 'cannonball' distribution of rounded nodules or tufts
of capillary-sized vessels in the dermis, with lymphatic vessels present at the periphery.
The natural history is slow progressive growth, after which it tends to remain stable
in size. Regression has been reported in some cases. Tufted angioma should be distinguished
from kaposiform hemangioendothelioma (KHE). Multiple tufted angioma and KHE may be
associated with Kasabach-Merritt syndrome (141000), which is characterized by severe
thrombocytopenia and consumption of coagulation factors (summary by Tille et al.,
2003).;
