Myositis ossificans masquerading as a recurrent spindle cell lipoma of the orbit.
A spindle cell lipoma developed in the right orbit of a 43-year-old woman whose medical history was only significant for chronic asthma. Sixteen months after nearly complete excision of the tumor, the patient presented with eyelid swelling, orbital pain, and a calcified apical mass as demonstrated by computerized tomography (CT). Recurrent tumor or a second neoplasm was suspected. Histologic examination revealed myositis ossificans. To our knowledge, this is the first reported case of myositis ossificans in the orbit.
