A vascular tumor is a vascular anomaly where a tumor forms from cells that make blood or lymph vessels; a soft tissue growth that can be either benign or malignant. [1] Examples of vascular tumors include hemangiomas , hemangioendotheliomas , Kaposi's sarcomas , angiosarcomas , and hemangioblastomas .
The predictive value and prevalence of lymphovascular invasion is strongly dependent on the type of cancer. In other words, LVI in one type of cancer may be much less important than LVI in another type of cancer. Generally speaking, it is associated with lymph node metastases [2] [3] which themselves are predictive of a poorer prognosis. [4]
Angiosarcoma is a rare and aggressive cancer that starts in the endothelial cells that line the walls of blood vessels or lymphatic vessels.Since they are made from vascular lining, they can appear anywhere and at any age, but older people are more commonly affected, and the skin is the most affected area, with approximately 60% of cases being cutaneous (skin).
Similar findings have been reported for colorectal cancer as well. [22] [23] There are two types of circulating tumor cell cluster, one that consists of cancer cells only is termed homotypic. A CTC cluster that also incorporates other cells including white blood cells, fibroblasts, endothelial cells, and platelets, is termed heterotypic. [24]

Intravascular lymphomas (IVL) are rare cancers in which malignant lymphocytes proliferate and accumulate within blood vessels. Almost all other types of lymphoma involve the proliferation and accumulation of malignant lymphocytes in lymph nodes, other parts of the lymphatic system (e.g. the spleen), and various non-lymphatic organs (e.g. bone marrow and liver) but not in blood vessels.

Vascular mimicry was first discovered in 1999 by Maniotis et al. who identified blood supplying channels in malignant melanoma that were composed entirely of tumor cell based structures. They found that cancer cells had taken on endothelial cell properties and were forming blood conducting vessels independent of normal angiogenesis pathways. [2]
