Orbital desmoid tumor in a pediatric patient

A 3-year-old girl with desmoid tumor of the right orbit initially presented with a 4-month history of unilateral ptosis and was subsequentially found to have fullness of the right upper eyelid. Computed tomography of the orbit revealed a soft tissue density in the superolateral quadrant of the right orbit. Histopathology from a biopsy revealed a desmoid tumor with positive margins. The patient subsequently underwent compete excision of the tumor and is presently doing well.
