A malignant neoplasm characterized by a vascular proliferation which usually contains blunt endothelial cells. Erythrocyte extravasation and hemosiderin deposition are frequently present. The most frequent site of involvement is the skin; however it may also occur internally. It generally develops in people with compromised immune systems including those with acquired immune deficiency syndrome (AIDS).
Features include always present findings: Recurrent herpes; and very common findings: Hypermelanotic macule, Abnormality of the lower limb, Neoplasm of the skin, and Macule. 26 total HPO annotations.
