Leiomyoma in the Ciliary Body Resected Ab Externo

ABSTRACT

A leiomyoma of the ciliary body is a rare tumor that is thought to arise from the neural crest tissue.It is difficult to differentiate this tumor from a uveal melanoma either clinically or pathologically. We performed a complete removal or the mass that had been suspected clinically as an intraocular inflammation or a malignant melanoma.However, it was diagnosed as a leiomyoma by immunohistochemistry and electron microscopy.
