Orbital nodular fasciitis simulating a dermoid cyst in an 8-month-old child. Case report and review of the literature.
OBJECTIVE
To report a clinicopathologic correlation of orbital nodular fasciitis that simulated a dermoid cyst in an infant and to review the literature on orbital nodular fasciitis.


METHODS
Case report; literature review.


RESULTS
A progressively enlarging subcutaneous mass superotemporal to the right eye that clinically resembled a dermoid cyst developed in an 8-month-old boy. Magnetic resonance imaging disclosed an enhancing, circumscribed, solid, soft-tissue mass in the anterior part of the orbit superotemporally. The tumor was removed intact by a superolateral orbitotomy. Histopathologic and immunohistochemical studies revealed findings consistent with nodular fasciitis, a pseudoneoplastic lesion marked by a proliferation of myofibroblasts.


CONCLUSIONS
Although nodular fasciitis in the ocular region usually occurs in adults and older children, it should also be considered in the differential diagnosis of orbital or adnexal masses in infants.
