Ciliary Body Melanoma Simulating Multiple Iris Cysts

Arch Ophthalmol. 2007;125(3):428-429. doi:10.1001/archopht.125.3.428

A 36-year-old man noticed mildly blurred vision in his left eye. At the pupillary margin, multiple dark-brown cysts were seen between the posterior surface of the iris and the anterior lens capsule (Figure 1 and Figure 2). A markedly elevated tumor, measuring 16 × 10 × 10 mm, was located superonasally behind the lens (Figure 3). The eye was enucleated and the histopathologic diagnosis was a mixed-cell melanoma of the ciliary body. Close behind the unaffected iris, numerous cysts arose from the ciliary processes on the tumor surface (Figure 4). The cysts were partly collapsed and the wall of each cyst consisted of a single layer of epithelial cells (Figure 5).
