HEMANGIOPERICYTOMAS Meaning and
Definition
-
Hemangiopericytomas are rare and potentially aggressive tumors that arise from the pericytes, which are cells that help in regulating blood vessel tone and permeability. They were originally classified as a variant of vascular tumors, and they commonly originate in the soft tissues of extremities, trunk, and retroperitoneal regions. However, they can also be found in various other locations such as the head, neck, meninges, and occasionally in bone. Hemangiopericytomas commonly affect adults, with a slight male predominance.
Histologically, these tumors typically display perivascular growth patterns, resembling a so-called "staghorn" pattern. They are composed of spindle-shaped cells with delicate blood vessels scattered throughout the tumor mass. Oftentimes, mitotic figures can be observed, indicating a potential for aggressive behavior.
Due to their rarity and variability in clinical behavior, the management of hemangiopericytomas can be challenging. Treatment usually involves surgical excision of the tumor with wide margins, aiming for complete resection. However, due to their tendency for local recurrence and potential to metastasize to distant sites such as the lungs and bones, adjuvant therapies like radiation therapy may be recommended. Close follow-up is necessary to monitor for any signs of recurrence or metastasis.

Etymology of HEMANGIOPERICYTOMAS
The word "hemangiopericytoma" has its etymology rooted in the combination of several components:
1. Hema-: Derived from the Greek word "haima" meaning "blood".
2. Angio-: Also derived from Greek, from the word "angeion", which means "vessel" or "container".
3. Peri-: A Greek prefix meaning "around" or "surrounding".
4. -cyto-: Derived from the Greek word "kytos", referring to a "cell".
5. -oma: A suffix indicating a tumor or mass.
Therefore, "hemangiopericytoma" is a term that combines elements related to blood vessels, cells, and tumors. It is used to describe a rare type of cancerous tumor that originates in the pericytes, which are cells surrounding blood vessels.
