MESECTODERMAL LEIOMYOMA OF THE CILIARY BODY PRESENTING AS ANTERIOR STAPHYOMA.
OBJECTIVE
To report two cases of mesectodermal leiomyoma of the ciliary body presenting as anterior staphyloma.


METHODS
Two case reports with cytopathologic correlation.


RESULTS
First patient (15-year-old boy) presented with a nodular lesion in the sclera. Second patient (31-year-old woman) was found to have a brown ciliary body mass. Growth of the lesion and extrascleral extension was noticed after several years of follow-up. Ultrasonography, light microscopy, and immunohistochemistry of both cases are described confirming mesectodermal leiomyoma of the ciliary body.


CONCLUSIONS
Mesectodermal leiomyoma, despite its rarity, should be considered in the differential diagnosis of uveal tract tumors. Clinically, the diagnosis is difficult and histopathological and immunohistochemical assesment is necessary to avoid inappropriate diagnosis and erroneous treatment.
