Solitary orbital myofibroma: Clinical, radiographic, and histopathologic findings. a report of two cases

This describes a non-interventional case series of 2 patients, aged 7 and 9 years referred to Oculoplastic Unit, both for evaluation of a gradually enlarging, painless, mass of the cheek. CT scan of the first case revealed left orbital floor destruction from a well-defined intraosseous mass. The second was a round circumscribed orbital floor tumor without bone destruction. Histological diagnosis of myofibroma was rendered in both cases. Solitary myofibromas are rare in the orbit. Their rapid growth and bony destruction can mimic malignant tumors. Complete excision with close follow-up is the preferred treatment. Solitary myofibroma should be considered in the differential diagnoses of fibrous tumors with bone destruction in the orbit.
