Inflammatory myofibroblastic tumor of the orbit presenting as a subconjunctival mass.
OBJECTIVE
To present a case of inflammatory myofibroblastic tumor in the anterior orbit and to describe its clinical features, diagnosis, and management.


METHODS
Case report and literature review.


RESULTS
A 10-year-old boy presented with diplopia and limited ocular motility in his right eye secondary to a subconjunctival mass in the right supranasal side. Incisional biopsy and debulking were performed. Histopathologic examination showed the proliferation of spindle-shaped myofibroblasts that were immunoreactive for smooth muscle actin and vimentin and infiltrate of inflammatory cells.


CONCLUSIONS
We believe this is the first case of an inflammatory myofibroblastic tumor found localized in the orbit.
