Capillary Hemangioma

Capillary hemangioma is the most common vascular orbital tumor in children. Capillary hemangioma accounted for 0.7 to 2.2% of all histopathologically proven space-occupying lesions in five orbital tumor series (Table 14.1).1-5 The real frequency of orbital capillary hemangioma is probably higher because many patients do not undergo a biopsy procedure. The clinical courses of eyelid and orbital capillary hemangiomas are similar.

FIGURE 14.3. (A) Preoperative, (B,C) intraoperative, and (D) postoperative photographs of a 5-year-old girl with an upper eyelid hemangioma (E). The lesion was predominantly composed of proliferating endothelial cells but it also contained occasional abnormally formed large blood vessels. (F) Positive immuno-histochemical staining (brownish color) with factor VIII depicts tumor components infiltrating into orbicularis muscle.
