Multinucleate cell angiohistiocytoma of the orbit.
OBJECTIVE
A 31-year-old had a five-year history of painless progressive swelling of her right upper eyelid.


METHODS
A mass was removed from the superonasal aspect of the right orbit.


RESULTS
The orbital mass was composed of a collagenous stroma with capillary channels and irregular giant cells. The findings were characteristic of multinucleate cell angiohistiocytoma.


CONCLUSIONS
Multinucleate cell angiohistiocytoma should be included in the differential diagnosis of circumscribed orbital tumors.
