Mesoectodermal Leiomyoma of the Ciliary Body

A 47-year-old woman is suspected of having a ciliary body melanoma (A). Histologic sections (B and C) show large ciliary body tumor composed of tumor cells in a fibrillar cytoplasmic matrix. Electron microscopy (D) shows a dense osmophiliic structure known as askeinoid fiber.Immunohistochemistry helped to confirm that this was a leiomyoma.(Case reported by J. Campbell et al. Ultrastruct Pathol 28:559, 1997.)
