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. An angioma refers to any type of benign vascular ...
The word was introduced in English in the modern medical sense around 1600. [27] Cancers comprise a large family of diseases that involve abnormal cell growth with the potential to invade or spread to other parts of the body. [2] [7] They form a subset of neoplasms. A neoplasm or tumor is a group of cells that have undergone unregulated growth ...
Hematological malignancies are malignant neoplasms ("cancer"), and they are generally treated by specialists in hematology and/or oncology. In some centers "hematology/oncology" is a single subspecialty of internal medicine while in others they are considered separate divisions (there are also surgical and radiation oncologists).
Infantile hemangioma is the most common vascular tumor. It is a benign tumor, which occurs in 4-5% of Caucasian infants, but rarely in dark skinned infants. [6] It occurs in 20% of low weight premature infants and 2.2 to 4.5 times more frequently in females. [7]
Endothelial progenitor cells incorporated in tumor vasculature suggests that this cell type in blood-vessel development is important in a tumor setting and metastasis. Furthermore, ablation of the endothelial progenitor cells in the bone marrow can lead to a significant decrease in tumor growth and vasculature development.
A central nervous system tumor (CNS tumor) is an abnormal growth of cells from the tissues of the brain or spinal cord. [1] CNS tumor is a generic term encompassing over 120 distinct tumor types.
