title: Chronic hematic cyst of the orbit.
abstract: Three middle-aged male patients had painless superior temporal orbital tumor causing globe displacement. Roentgenograms revealed superior temporal orbital tumor with lysis of bone. Surgical excision and curettage completely removed the lesions, which extended from the frontal bone to the periorbita and the dura. Histologically, these were cystic lesions containing a granulomatous reaction to blood breakdown products, including cholesterol clefts, hemosiderin, giant cells, and hematodin, consistent with chronic hematic cyst. A fibrous pseudocapsule formed the cyst wall.
