Capillary hemangioma has been referred to as a vascular tumor when it presents in the orbit and has been known as port wine stain when it presents extra-orbitally at the head and neck (Flis and Connor 2005). Capillary hemangioma is an inborn lesion predominantly found in small children that shows a tendency toward spontaneous involution up to the 5th year of life. However, capillary hemangioma may displace other orbital contents... 

Capillary malformations (CMs), because of their appearance, have traditionally been referred to as port wine stains and incorrectly as capillary hemangiomas. They represent maldevelopment of capillaries and present as well demarcated skin discoloration. CMs initially have a pink or red color and become more purple as children age. CMs frequently occur with other vascular anomalies. In Klippel-Trenaunay syndrome, they occur on the trunk or lower extremity and are associated with limb hypertrophy and widespread venolymphatic malformations. In Sturge-Weber syndrome, the CM is typically in the VI (first division of the trigeminal nerve) distribution on the face and is associated with underlying ophthalmologic and leptomeningeal VMs and CMs. 

Some of the vascularized tumors that have shown to be beneficed by a preoperative embolization include soft tissue and bony hemangiomas in adults, capillary hemangiomas in children and malignant synoviomas.

Hemangioma is a purplish or reddish benign tumor consisting of a network of interconnecting capillaries. 

Strawberry hemangiomas are congenital vascular lesions characterized by endothelial hyperplasia during the proliferative phase. The development and proliferation of capillary endothelium requires the presence of angiogenic factors, such as vascular endothelial growth factor. Epoetin has a proliferative effect on endothelial cells and can induce angiogenesis (104,105). 

A hemangioma is demonstrated as a hyperechoic tumor in the submucosal layer. Calcification is occasionally seen inside the tumor (Fig. 19.7). Since the blood flow of the capillaries making up the tumor is extremely slow, it is difficult to detect blood flow signals using the conventional color Doppler method. 

The rare benign tumors of the cervix comprise capillary or cavernous hemangioma, lymphangioma, papillary adenofibroma, adenomyoma, fibroadenoma, and mesonephric papilloma. 

Among vascular diseases that may chnicaUy appear as tumor-like lesions, there are capillary and cavernous hemangioma, orbital vein anomaly, venous-lymphatic malformation, orbital vein thrombosis, and carotid-cavernous fistula. When large, vascular lesions oftentimes are not confined to one orbital space alone, and they may extend to extra-orbital locations of the head and neck (Flis and Connor 2005).
