Composite Hemangioendothelioma Settled in the Paraspinal Region: A Rare Case Report.

Composite hemangioendothelioma (CHE) is a very rare, low-grade malignant vascular tumor. It is most commonly seen as one or more nodules on both sides of the fingers and toes. This tumor rarely settles in the paraspinal muscles. The age of onset is usually between 21 and 72 years, with an average age of 39.5-41 years. Treatment is with gross total removal of the lesion. We present a case of a 54-year-old male patient with a 2-year history of low back pain. Lumbar spine magnetic resonance imaging revealed CHE in the right paravertebral muscle in the posterior vicinity of the transverse process between the right paraspinal muscle planes. The entire mass was removed grossly. The definitive diagnosis of CHE was made histopathologically. This is a rare case of CHE that had settled in the paraspinal region.
