Solitary myofibroma of the sclera.
OBJECTIVE
To report a novel case of solitary myofibroma involving the sclera.


METHODS
Case report and review of the literature.


RESULTS
A 19-year-old woman had an expanding and painful epibulbar mass clinically diagnosed as nodular scleritis that did not respond to anti-inflammatory therapy. A biopsy showed a proliferation of spindle-shaped cells that reacted strongly positively with immunoperoxidase stains for vimentin and smooth-muscle actin. The diagnosis of solitary myofibroma was made. Six months postoperatively, the patient was well, and the lesion had not recurred.


CONCLUSIONS
Myofibroma should be considered in the differential diagnosis of an epibulbar mass, especially in the setting that would mimic nodular scleritis.
