Kaposi sarcoma. Definition

Medical Definition: Kaposi sarcoma

Malignant tumor of vascular origin, characterized by the appearance of multiple cutaneous nodules, usually in the lower extremities. Histologically is a mix of channels and vascular spaces lined by tumor cells and solid masses of spindle tumor cells. In patients with AIDS is presented as an aggressive lesion, growth and rapid expansion, unlike the classical sporadic, much slower evolution.
